Dial back your iPhone 3G or 3GS to a previous iOS
As mentioned before, iOS 4.0 on the 3G iPhone is not awesome—it’s slow, over heated, quickly drains the battery and is generally unstable. And though Apple is apparently aware of the problems and is working on fixing the situation, the rest of us need to get stuff done in the meantime.
My friend, Mike Bjorndal ( @mbjorndal ) pointed me to this iHackintosh article that allowed me to put my iPhone in DFU mode, restore an older firmware and boot back out of DFU mode again. After restoring my apps and settings in iTunes, I was back in business with a faster 3G iPhone experience running an older firmware.
Keep in mind, many of the apps you may be running now might require iOS 4.x and will be inaccessible from an older version of the OS. I take no responsibility for any lost data. Backup and then backup again…and then reconsider doing this hack.
Apple has pushed an Apple TV update tonight that brings the device’s software to version 2.3.1. Unfortunately, the software update procedure on Apple’s home theater device does not offer any list of what changes with each upgrade, so we are forced to just download and hunt around until we find improvements.
