f0recast is a very handy program developed by iH8sn0w to determine if your iPhone, iPad or iPod Touch can be jailbroken (or unlocked). If you are new to jailbreaking and unlocking, this is an essential tool for you.
The latest version 1.3 released by iH8sn0w a few hours ago will give you the latest “forecast” on jailbreaking/unlocking your device.
In the screenshot above it shows that there’s no software unlock available for iPhone 4 and it’s only possible using a Turbo SIM.
It’s available for both Windows and Mac.
According to our supplier, the manufacturer of Gevey Pro Plus in China is in their final stage of testing the final version of the Gevey Turbo SIM series.
UPDATE: You can now unlock any AT&T iPhone officially and permanently using this.
Gevey Pro Plus is a more intelligent Turbo SIM that does all the unlocking steps for you – making the unlock for iPhone 4 “virtually untethered.” Simply insert your SIM card, and it will do everything for you in the background. Essentially it still dials 112, switching the Airplane Mode On/Off, but you will not see all those on the screen; just as the packaging says “Without Any Operation.”
The whole automation will take between 90 and 120 seconds. This latest line will come in a bright yellow packaging, and possibly with a wider chip and custom SIM tray that doesn’t require you to trim the corner of your Micro SIM card.
That’s the only information we have now, as soon as we have the price (to be very competitive), we’ll setup a pre-order page on our store.

It’s been a while since we last heard about baseband related hacks from the iPhone Dev Team.
sherif_hashim is bringing some good news for us today – he managed to erase the files on a baseband chip that has modem firmware 6.15.00. Technically, according to him, you can reflash the baseband with an earlier version of iOS that has baseband 5.13.04 or lower.
In his Twitter:
Successfully erased the 6.15 BB files http://twitpic.com/51co5p , should accept new BB flash files now, or at least i thought so :)
This is probably the best news we’ve heard since… mmm…. ages ago.
The image above shows Firmware Version as “unknown,” pretty much like a hard disk ready to receive data for writing.
This is how we believe the process should work:
- Erase baseband 6.15.00 files with the hack developed by sherif_hashim (Erasing a baseband chip is very risky! You may end up bricking your device)
- Create custom firmware with baseband 5.13.04 or lower, for iPhone 3G, restore directly via iTunes with firmware 4.0.1 or below, for 3GS, if you have SHSH for 4.0.1, you restore to this version
- Restore successful with baseband 5.13.04 or lower
- Jailbreak and install ultrasn0w 1.2.3 to unlock
- GPS fixed!
Let’s hope that there will be more good news as people are desperate to get their GPS back. At the same time, those who are stuck with baseband 5.14.02, 5.15.04 and 5.16.02 may finally be able to see the light at the end of the tunnel.

There are cases when your iPhone is stuck in recovery mode and you need to save its SHSH via TinyUmbrella locally to allow you downgrade to an earlier iOS version. Fortunately, there is a relatively easy way to do this.
Each iPhone comes with an ECID (Exclusive Chip ID) which is a 16-digit hexadecimal number. Once you have the ECID, you can create a custom iDevice in TinyUmbrella to save your SHSH blobs locally from Cydia.
1. Download USB device viewer
2. Launch the program and check Show Config Descriptors option under Options.
3. Go to File > Refresh.
4. Find Apple Recovery (iBoot) USB Driver option in the left-panel. On the right panel, you can see the ECID in the descriptor fields. It should be something like ECID: 000xxx…
5. Now download the latest version of TinyUmbrella [current version as of today is 4.33]
6. Launch TinyUmbrella > go to Advanced tab and check Request SHSH from Cydia.
7. Go to General tab and click on Manual ECID button. Enter Display Name (any name you wish), ECID and select your iDevice model. Click Create Custom Device.
8. Choose the device that you just created under Custom Devices on the left panel and click Save SHSH.
9. Click Start TSS Server and restore using original or custom firmware with iTunes once your SHSH is saved locally.
