On June 7, on the day of the release of iOS 5 beta for iOS application developers, MuscleNerd warns all owners of iPad 2 3G tablets not to update to iOS 5 because they will no longer be able to downgrade to iOS 4.3.3 because they will receive an error during the downgrade process. Then MuscleNerd said that the baseband in the iPad 2 3G cannot be downgraded to a lower version and during the downgrade process from iOS 5.0 to 4.3.3 we will receive an error, the tablet will enter Recovery Mode and we will not be able to remove from that state until a bootrom exploit appears for the A5 chip.
Many were afraid to update to iOS 5 after this announcement, I have to admit that I did the same, taking what MuscleNerd said then. I asked MuscleNerd and iH8sn0w repeatedly if the downgrade process for the iPad 2 3G is similar to the iPhone 4, that is, if the baseband downgrade would also be done, but none of them answered. Reading about others who returned to iOS 4.3.3 on the iPad 2 3G, I got up the courage and last night I updated and activated my tablet without having it registered to a developer's account and everything works without problems, even the internet through the card .
Seeing that I have iOS 5 beta 2 functional, I thought of downgrading to iOS 4.3.3 to see if it is possible or not. To my surprise, everything went without the slightest problem, after a few minutes I had iOS 4.3.3 on the tablet and everything was working without problems and even the baseband was reset to the value from iOS 4.3.3. To downgrade, I only opened iTunes, selected iOS 4.3.3 using shift + restore and waited a few minutes, but it must be mentioned that I did not use any kind of SHSH.
In conclusion, we can downgrade from iOS 5 beta 2 to iOS 4.3.3 on iPad 2 3G without problems and MuscleNerd lied when he said this was impossible. Moreover, neither he nor iH8sn0w have confirmed in any way that the baseband is downgraded like the iPhone 4, something that happened to me during the 2 downgrade processes done last night and today.
