How To Identify Fake GEVEY Sims & Avoid Getting Scammed

Ever since I unlocked my iPhone 4 using GEVEY Sim, I was facing battery drainage problems and also the area around the sim slot was getting over-heated. I thought my battery drain was due to iOS problems or over-usage.

Today I was going through Yahoo! Answers and found this question. I found the answer posted xbowlover interesting. Here’s what he says about the difference in original and fake GEVEY Sims:

The main difference is they use different chips. The original one uses F981 chips. You can see the digital numbers on the gevey SIM (The black part). And the copy one uses F300 chips. The manufacturers usually wipe the numbers out, and you will not see any digital numbers on the black part.

Only original Gevey SIM comes with F981 as they have bought out this chip in the market, so others can only use F300. And the original Gevey SIM drains less battery and has better signal reception.

You may also want to read: Difference Between Real & Fake GEVEY Pro SIMs This immediately struck me and I got a pin and removed the GEVEY Sim tray from my iPhone and found that there isn’t any number on the black part of the IC chip. Also, I thought to do some Google research on F981 chips used in GEVEY. And I found a Chinese site telling about the F981 & F300 chips.

Here’s what it reads after using Google Translate (I’ve improved the Grammar):
There are many counterfeit GEVEY sims in the market, all are very similar in appearance, but they have a lot of problems. They likely cause unnecessary damage to the iPhone. Your eyes cannot easily distinguish between the original and counterfeits.
After the Genuine GEVEY Sim is exposed to bright light, you can see the black chip has F981 written on it.

Following is a picture of genuine GEVEY:

Counterfeit GEVEY sim uses F300 chips. Fake sims use the process of hand-welding which is quite rough. F300-chip voltage ranges from 3.0 ~ 3.6V, so the SIM card operates at 3.0V. The original GEVEY sims operates at 1.8V. Also, the thickness of F300-chip is twice the thickness of the F981-chip. This can lead to GEVEY tray being stuck in the iPhone. It cannot easily get in or get out.
  • The surface of the F300 chips doesn’t have anything written on it. Here is the picture of fake GEVEY chip or F300 chip:

(Unfortunately, the GEVEY chip I’m using also doesn’t have anything written on it)
Use of counterfeit sims is related to risks and consequences. The appearance and size is the almost same, but the difference is in the power consumption of the sim. This greatly reduces the standby time of the iPhone.
Here are the problems caused by counterfeits:
  1. Increased power consumption, mobile phone standby times are noticeably shorter.
  2. SIM card can cause problems ranging from permanent damage to the possibility of burning.
  3. The Baseband chip can be seriously damaged. had posted a tutorial on this page, but it seems to be gone now. Please tell us if you are facing the same problems, like battery drainage and over-heating of the sim in the comments below. Also tell us if F981 is printed on your GEVEY chip.
And new buyers, don’t get scammed. Buy only after checking if F981 is printed on the GEVEY chip.

Update 1: Here are two more pictures to support this topic:
Click here to enlarge Click here to enlarge

Click the images for a larger view. You can see F981 printed on the IC.

I got it from Dill Huang’s Singularity blog. He was the first person to post how the GEVEY sim works, so he must’ve got the original GEVEY sim then, because at that time GEVEY was not launched to the public and chances of getting clones were zero.
And certain persons have reported that the GEVEY Pro sim (ordered directly from doesn’t have anything written on the IC chip. So, it may have happened that the company producing GEVEY must have stopped printing F981 and other things on the IC chip. But, this will be the case only for the recent GEVEY sims. The older GEVEY sims which were brought in the initial period of the launch must have F981 printed on them.

Update 2: I got a Youtube video and slides which show the difference between original GEVEY sim and fake GEVEY sim

Link to Youtube video – This video shows a complete comparison of original and fake GEVEY sims (including the puter cover, the plastic covers, the manual, IC chip, etc)..

Link to Scribd slidesThis shows the pictures of original & fake GEVEY sims

Some features of the Original GEVEY sim that I learnt from the Youtube video:
  • The original GEVEY sim shows an “English Menu” whereas the fake ones show “Chinese menu”
  • The sim tray of original GEVEY is of superior material and has “GEVEY” engraved on it, while the fake one’s sim tray if of lower quality and it has “GEVEY” printed on it, not engraved
  • The circuit design of both is same, just the original one has F981 printed on it
The video also says that the GEVEY sim used in ApplenBerry’s first demo video had some extra design. The design changed in the later productions of GEVEY.
I must tell people here that both GEVEY Sims work. You can call, send/receive texts, etc. But it’s the matter of quality, the GEVEY Sim from ApplenBerry gives you 100% quality, whereas the GEVEY sims from Chinese suppliers are clones. They are not 100% same as the original ones, but let you use your iPhone 4 to make calls, SMS, etc..

Enable Facebook video calling in Lion

Facebook’s new video calling feature is specifically designed for each browser and OS combination out there.  Unfortunately, Facebook didn’t account for those people using Lion (You’ve got a week Facebook).

The fix is easy however: Just change your Browser user agent to something a little more traditional and you are video chatting.
For instance, in Safari, hit up Safari 5.1-Mac and you are golden.

iPhone Dev-Team Releases Tethered Jailbreak for iOS 4.3.4

The iPhone Dev-Team has released RedSn0w 0.9.8b3 which can perform a tethered jailbreak on iOS 4.3.4.

For the convenience of kernel hackers like @comex and @i0n1c, we have a new redsn0w 0.9.8b3 that supports a TETHERED jailbreak for iOS 4.3.4 on all devices that have 4.3.4 except the iPad2. The vast majority of people will want to stay back at 4.3.3 because that's where the untethred jailbreak is! There are no new features in 4.3.4 - only fixes for jailbreak exploits.

Also, this is a good time to remind everyone (since we're still seeing confusion about this): iPad2 owners with a baseband (3G or CDMA) cannot currently use saved blobs to go back to 4.3.3 once the signing window is closed. This is unlike every other device, so don't be confused! iPad2 owners with basebands should stay away from all updates to maintain your jailbreak!

You can download RedSn0w 0.9.8b3 from here: (Mac, Windows)

How to Jailbreak Your iPhone 4/3GS Using RedSn0w (Windows) [5.0b4]

These are instructions on how to jailbreak your iPhone 4 on the 5.0b4 firmware using RedSn0w for Windows. Since iOS 5.0 has not yet been released these are instructions for developers only. This procedure will cause you to upgrade your baseband potentially ruining your chances for an unlock, it will not hacktivate so you must have your UDID registered with a developer, and it is tethered.

Step One
Create a folder on your desktop called Pwnage

Download RedSn0w from here and place it in the Pwnage folder. Likewise, download the latest 5.0 firmware from the iOS Dev Center and place it in the same folder.

5.0b4 (GSM): iPhone3,1_5.0_9A5274d_Restore.ipsw
5.0b4 (3GS): iPhone2,1_5.0_9A5274d_Restore.ipsw

Extract the RedSn0w zip file into the same folder.

Since this is a tethered jailbreak you must use Redsn0w to help you boot back into your jailbroken device if its powered off for any reason. Simply connect your iPhone to the computer, launch RedSn0w, select Just boot tethered right now from the options window and click Next to have RedSn0w boot your device.

iFaith v1.3 Released, Fixes DFU Loops And Other Bugs

iH8Sn0w has released a new version ofiFaith v1.3. iFaith v1.3 comes with some major changes so we cannot say it’s a minor release. One the major issue which has been fixed in this release is “DFU Loop”, some users were stuck continuous DFU Loop after restoring back to stock or jailbreaked firmware. The problem has been fixed now, complete change log is given below.

iFaith v1.3 supports following devices :

Apple TV 2G
iPad 1
iPhone 3GS
iPhone 4
iPod Touch 2G
iPod Touch 3G
iPod Touch 4G

As iFaith uses DFU bootrom exploit to work and we don’t have any bootrom level exploit for iPad 2 to iFaith v1.3 won’t support iPad 2.

Release Notes of iFaith v1.3:
For iOS 3.1.x/3.2.x/4.0.x/4.1/4.2.1/4.2.6/4.2.7/4.2.8/4.3/4.3.1/4.3.2/4.3.3
DFU Loops were being caused on devices that had the factory certificate.
On this new version. When building the signed IPSW. If you were getting
a DFU loop, say “NO” to the prompt about using the standard
signing certificate.
* You can now use TinyUmbrella blobs to build a signed IPSW.
[Change Filetype in browse dialog to "TinyUmbrella SHSH blobs".]
* Now adds ECID to beginning of the SHSH filename after dumping.
* Now adds ECID to beginning of the IPSW filename after being built.
* Cleaned up code + payload.
* Its not possible to add iPad 2 support until a bootrom exploit arises.
Want to know more about iFaith, please read below:
if you want to restore your iDevice to a previous iOS, the process will fail unless you have the blobs for that particular iOS version saved and use such tools as TinyUmbrella.
But, saving the blobs for an iOS version can only be done as long as Apple still signs that iOS. When a new iOS version is being released, Apple stops signing the previous version and if you didn’t save your blobs you can kiss your downgrade goodbye. Or that’s how it was until today. Because iFaith takes care of this problem.
If your iDevice is susceptible to the Limera1n jailbreak ( all iDevices except iPad 2, iPhone 3G and iPod Touch 2G – last two are forever jailbreakable ) you can use iFaith to dump the blobs from the device.
For example, if your device is running a prior iOS to 4.3.3 ( latest release to date ), you can use iFaith to get the blobs for your iOS version even if Apple stopped signing it.

Jailbreak iOS 5b5 on iPhone, iPod touch, iPad with Redsn0w 0.9.8b5

The Dev-Team has already upgraded its Redsn0w 0.9.8b5 to jailbreak iOS 5 beta 5.
As for the previous iOS 5, the jailbreak is possible but it’s tethered, meaning that you have to plugin your iOS device to the computer and boot it in
tethered mode using Redn0w

Please note that you’ll not be able to unlock your iPhone using this method. An unlock for iOS 5 is still not possible.

This jailbreak does not work for iPad 2. If you have an iPad 2 jailbroken with JailbreakMe 3.0, stick to it because an untethered jailbreak for iPad 2 will not be available for a while.

This jailbreak will work on iPhone 3GS, iPhone 4, iPod touch (third and fourth generation) and iPad 1.

iTunes Match Beta Now Available to Developers (iTunes 10.5 Beta 6.1.)

Apple has just made iTunes Match available to developers for the first time. The announcement comes via an email prompting developers to update to iTunes 10.5 Beta 6.1.

iTunes Match beta is currently available to developers in the United States. Beta subscribers will receive iTunes Match service during the beta period plus an additional 3 months for free with their 12 month paid subscription.

To get started with iTunes Match, download the current version of iOS 5 beta and iTunes 10.5 beta 6.1 with iTunes Match. Once installed, choose Turn On iTunes Match from the Store menu, and click "Subscribe for $24.99."

Please note that you must maintain a local backup of your iTunes library as well as any music you add to iCloud.

Video Walkthrough of New iTunes Match Feature

Interested in the new iTunes Match feature? Take a look at this video walkthrough of how it works by IGM.

If you want all the benefits of iTunes in the Cloud for music you haven't purchased from iTunes, iTunes Match is the perfect solution. It lets you store your entire collection, including music you've ripped from CDs or purchased somewhere other than iTunes. For just $24.99 a year.2

How It Works:
iTunes determines which songs in your collection are available in the iTunes Store. Any music with a match is automatically added to your iCloud library for you to listen to anytime, on any device. Since there are more than 18 million songs in the iTunes Store, most of your music is probably already in iCloud. All you have to upload is what iTunes can't match. Which is much faster than starting from scratch. And all the music iTunes matches plays back at 256-Kbps iTunes Plus quality - even if your original copy was of lower quality.

Notice the video below shows that you can both stream and download from iCloud.

Redsn0w 0.9.8b6 Released To Jailbreak iOS 5 Beta 6

Apple has released iOS 5 Beta 6 recently, Now Redsn0w 0.9.8b6 is here to jailbreak the latest Beta of iOS 5.

Click here to enlarge

We’ve released redsn0w 0.9.8b6 to jailbreak iOS5 beta6 (point it directly at the beta6 IPSW). Two important notes about this version:

(1) Please let your device boot normally to IOS5b6 and do a clean shutdown (slide to power off) before jailbreaking.
(2) Boot logos have intentionally been disabled for now, so you’ll see a black screen on tethered boots (you can re-enable logos or verbose boot with command-line options if you really want them back). Due increased sensitivity to abrupt filesystem shutdowns in IOS5b6, it’s very important that you do a clean shutdown before running redsn0w.

Note: This is a tethered jailbreak meaning that you will have to jailbreak your device every time the divece reboots or loses power.
