IPhone is stuck in recovery mode. HELP?

Ok I’m sorry for posting another iPhone help post, but this is my last resort. I have looked at every page I can find one the internet and nothing is helping me, I have asked on ModMyiFone.

I have a 1.1.4 iPhone and I am on Mac OSX 10.5.3 It started this morning when I turned on my iPhone it was in recovery mode and now it wont get off it. It is an activated and jailbroken iPhone but not unlocked. The night before I had been installing lots of apps, that might be the problem.

I tried restoring it and deleting the old restore files and re restoring it, I also tried re starting it in normal mode with ZiPhone but nothing it just gets jammed.

Does any one know how to fix it.
