Details: iPhone 4 4.3.3 Jailbreak - www.jailbreakme.com Well this time I've done it. I decided to install an app from Cydia (for the life of me I cannot remember which). It downloaded the app correctly, then the phone rebooted (respringed?) itself. That's where it stopped. When it rebooted it went to black, and it has stayed like that for 2 nights. I've tried every possible way to fix this. When I connect it to my PC iTunes doesn't even recognise the iPhone. I've tried entering DFU mode manually (by physically pressing the sleep + home buttons), by using RecBoot, iReb, TinyUmbrella and Fixrecovery. None of them has worked. The screen stays as black, that's it. Is there any way to fix this problem? My very last resort is to send it off to Apple but I'm worried that they won't do anything about it or charge a substantial amount because I've gone and jailbreak my phone.
