i have at&t and I jailbroke my phone, I have the installer app, and have had it over a week. Today I installed several apps including summerboard and now my phone doesnt work. I can't listen to voicemail or hear people when they call. If I answer the mute and speaker buttons will be already on. Text message works fine and so do all my apps but I cant connect to any wifi network. I've tried restatting and it doesnt matter. In thinking one of the apps disabled it. How can I fix it without losing everything? Or is the only answer restoring it? I'm away from my computer for 3 days that is why I ask. Also I am unable to uninstall summerboard. I need help, anybody who knows what to do will be greatly appreciated!
