In the last few days I have noticed that a lot of people are interested in an unlock solution for iOS 4 for iPhone 4 and iPhone 3GS. Unfortunately for you I don't have any good news, in fact I don't have anything new because the Dev Team hasn't said anything about the release of any unlock solution. The latest news related to the launch of an unlock solution featured MuscleNerd's "story" which claimed that the unlock solution developed by him only worked on a card belonging to the T-Mobile operator in the USA.
To answer your possible questions: no, the Dev Team will not release an unlock solution for iOS 4 until iOS 5 appears in iTunes. In fact, it is very possible that the Dev Team will not release an unlock solution for iOS 4 and will release one only for iOS 5, and all those who want to unlock will have to update. If the Dev Team has an exploit for the iOS 4 baseband, rest assured that they will not reveal it now and wait for Apple to release iOS 5 with an updated baseband that will more than likely contain that vulnerability. If we continue with this idea, the Dev Team will not release an unlock solution until the iPhone 5 is available on the market in the hope that its baseband will also be exploitable. In conclusion, you want to unlock, use Gevey, iPad baseband or wait for iOS 5.
Now let's talk a little about the Gevey cards whose days are numbered at the moment. Starting with iOS 5 beta 2, Apple blocked the possibility of decoding an iPhone 4 using a Gevey 3G card. If you now update to iOS 5 and update your baseband, you will not be able to decode with Gevey, but if you downgrade to iOS 4.3.5, you will be able to do this. As soon as iOS 5 will be officially launched, you will no longer be able to downgrade the baseband at all, so I warn you from now on not to update to iOS 5 when it appears if you use a Gevey card. After the release of iOS 5, these cards will become unusable and you will have to wait for an unlock solution from the Dev Team.
That's all about unlock and iOS 5, I hope I covered all your curiosities.
