Hey guys, I have a big problem with my iphone 3g. (ios 4.2.1with jailbreak) Yesterday my iphone 3g was acting strange, itunes gave a lot of errors when it was updating my apps, so I decided to reset my iphone. So I went to settings-->general-->reset-->erase all content and settings. The iphone displayed a message saying that this could take an hour. Now my iphone is stuck on the bootscreen, I tried to restore it using itunes a dozen times but I keep getting errors (mostly error 6). I searched the internet and found on a forum that I should rejailbreak my iphone, so i did using redsnow but the jailbreak keeps crashing during uploading kernel (or something like that, can't remember exactly) Now when I start my iphone it dipslays the "connect to itunes" picture. I also tried to restore it to fw 3.1.3 but that doesn't work either, itunes stops halfway and dislays errors. What should I do now, please help me?!?
