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.
