I recently jailbroke my iPhone 3g ios 4.2.1 and it's been crashing ever since. I did have Winterboard at one point, along with several themes and tweaks. It started crashing, freezing, and taking forever to do anything I needed. Before I jailbroke the phone, Safari would crash a lot and simple things like pulling up my text conversations would take AGES but it was nothing compared to the problems I'm experiencing now. I'm no hacker and have only been following online tutorials so I have no idea how to fix this. I downloaded CrashReporter and the first time it crashed after I downloaded that, it showed me which tweak it thought was causing the problems. I deleted it and continued to experience problems. At that point, CrashReporter stopped showing me anything at all. I then tried trouble shooting, deleting things one at a time, every time still experiencing springboard crashing. I now have nothing but Cydia. No Winterboard, no themes, no tweaks, nothing. But it's STILL crashing. All the time. What can I do at this point? I read about resetting under settings and general. I also read about completely restoring my phone. I almost want to restore and go back to the way it was because this jailbreaking is really affecting how my phone functions and I'm going to end up destroying it in some horrible way if I can't figure this out. However, I really really love the tweaks and customization options of jailbreaking and I don't want to lose that. Is there anything I can do?
