A quick timeline of my problems: --bought iPhone 4 at launch --jailbroke last week using JailbreakMe --smooth sailing for a week or so? No issues, errors, etc. --Yesterday, I tried to open Cydia and started getting database errors. Tried to rejailbreak it, that didn't fix Cydia, so I left it alone for the time being. --earlier today, I opened my camera roll and was confronted with an error message saying that it had to "restore" my photo library...it went through the restore and then said I had no pictures saved in my camera roll (I had had around 1600!). After a brief panic, i opened the camera roll again, let it go through the restore again, and the photos were back. And now my current, major issue... --about two hours ago, the phone just died. Completely. It was fully charged (I had just taken it off the charger about ten minutes prior) and I had my rss reader open (MobileRSS). Without warning, the screen dimmed and went black. Pressing the home button=no response. The power button=no response. So I plugged it into my computer to see if I could restore it and again...no response. I held down the power button + home button for ten seconds, released the power button, and after a few seconds the computer recognized it...but the screen remained black. iTunes popped up and told me to restore it, so I tried. The restore failed. Error 21. The screen came on...kind of. Just a bright white screen at this point. after a minute or so, it goes black again and the phone is still dead. So to recap...I'm not getting the "recovery mode" screen on my phone. I can't get the Apple logo, anything. It appears to be stuck in DFU mode but it won't restore because of the Error 21 issue. I've tried everything--uninstalled iTunes completely and reinstalled, tried it on a different computer, etc. Nothing is working. I've googled it to death and all I keep seeing is "put it in DFU mode and recover it, it's impossible to brick an iPhone"....but absolutely nothing is working to restore mine. Any ideas?
