Jail break doesnt work for me anymore ! Need HELP ASAP

[trickiscool]

Hi i have a 2g iphone that was on firmware 3.1.2. I was able to unlock it and get a t mobile sim to work. However, just now my phone ran out of battery and when i turned it on again, it went back to the screen where i can only make emergency calls. I tried to black rain it again and it did not work? Anyone got any ideas?

I was reading around and someone said it might be an app i just installed. I just installed the bank of america app and the ebay app. Also, i dont have an atandt sim card anymore to put in my phone so i can restore using itunes? WHAT DO I DO!??!?!

well i installed a few apps from cydia a while back and nothing was wrong. I think only bootneuter. If its any help my phone can still recieve calls? I am afraid that my only option is to borrow a sim card and start all over?
