Hi, I am desperately in need of helps. I updated my phone 4 to ios 5 while preserving the baseband with custom firmware. Everything went through fine and working all jb apps and app store apps till last night. I installed atomic web browser and it will open and then crash instantly. I uninstall and reinstall with no luck. So I deleted it. After that none of my 3rd party apps are working. I cannot open them. They will just show splash screen and then quit but all the built in apps such as camera, messages etc are still working fine. -I tried to take out all the apps through itunes and resync with no luck. -I tried to restore it through itunes but it just keep giving me 1600 error even though I already put the phone in pwned dfu mode. -I tried to restore with official firmware(knowing the baseband will get updated) and it gave me error 11. -Also tried to change the host file and put back the original without luck. -I tried reset the network and all settings. Still doesn't work. -I tried to erase all content and settings but the phone just keep crashing and giving me endless spinning wheel. ( have to hard reboot) -install random app from itunes to fix but no luck. -changed itunes password. So I have tried all the possible way of fixing the problem but nothing is working. Can you guys help me fix it? Thanks a lot.
