Been having some issues with my iPhone 3G lately, it seems to be getting worse, like a person with an illness which is freaking me out. First was the iTunes error when trying to connect to iTunes, 0xE800006B, then I went to shut it off last night for bed and it got stuck in the Apple screen for some time. It is giving me the "This device is not for iPhone" when I use the car adapter. It's just been weird. Might be time for a full restore which is pretty time consuming but may have to be done. Any other suggestions?
