iPhone 4 to iOS 4.2.1 or above, you might be aware that there is currently no unlocking software available for the accompanying basebands. Naturally, we'd imagine the Dev-Team Gevey SIM provides janky but jailberak-free unlock for iPhone 4 on iOS 4.3

Gevey SIM

If you've updated your iPhone 4 to iOS 4.2.1 or above, you might be aware that there is currently no unlocking software available for the accompanying basebands. Naturally, we'd imagine the Dev-Team will soon provide a remedy for this lack of freedom, but for now, Gevey has you covered... somewhat. For $70, this imposter SIM promises to unlock, without the need to jailbreak, all the current basebands found embedded within 4.0 - 4.3. In the video after the break, it appears multiple -- and frankly, just plain inconvenient -- steps are required to get the kit working on your iPhone. What's more, apparently you'll need to do all of this again if you switch off the phone. Oh, and we should mention this involves snipping off a corner on your SIM card, and carriers tend not to like that. Our recommendation regarding this contraption? If you're absolutely in the need of a carrier unlock and have the cash, proceed with caution. Otherwise, patience is your answer.
