So I jailbroke my iPhone 4 (4.2.1) with redsnow a few days ago and have been enjoying the freedom of choice. lol... Up until now that is. About an hour ago I bought a biteSMS license and reopened the application to activate it, everything activated fine. Then I told a friend to send me a quick text so I could try it out. At that point I put my iPhone to sleep using the button and waited for the text. I heard the text tone, picked up my phone and noticed the screen wasn't on. So I clicked the home button, still no screen. I tried this several times and the screen wouldn't turn on. So, I figured I'd connect it to my PC and boot tethered through redsnow, and at first that seemed to work. But after taking 15 minutes on the pineapple logo it restarts with the apple logo. It still wouldn't boot. It's just in an endless cycle of rebooting itself now after about 10 minutes on the apple logo. I tried rebooting several more times with redsnow, but it does the same sequence over again. HELP! My life is on this phone!
