I have zero issues with Bite, on an i4 running 4.2.1 and now 4.3.1. About a year ago it had some issues with QuickReply (typing lagged) but that's about it. I use it daily, never any trouble while using it. It has never crashed my phone. I would look to your system for the answer, since, for so many of us, it works perfectly.
 
Ive been running bitesms for almost a year no problems, now with new update I cant quick reply it locks up my phone.
 
Though I have my blobs backed up, it looks like they're making it harder to go back a firmware version now, as when I roll back to 4.2.1 and it's installed it keeps going back into DFU so I cant touch a thing unless I put 4.3.1 back on. Not sure why as of yet, but I'll keep trying till I can get it, as now I can't view video messages on 4.3.1 >_<.
 
Tons of problems here...

Running iOS 4.3.1 in iPhone 4 and having all of the above problems, although I'm glad it's BiteSMS causing them, because I had no idea what was wrong. My quick reply works, although it's laggy on the lock screen. If I choose to "Open" the text it just goes to the last app or screen I was on. Worst of all, my phone has been crashing AT LEAST a half dozen times a day. I suspected Bite as the problem. I guess I'll try the beta and see if it helps.
