I've tried a bunch of the things other threads have said, restarting, deleting cache, deleting old messages, downloading handcent SMS, deleting Facebook, nothing seems to work. I can even text myself, the text gets received before the app says it failed! This is incredibly frustrating and I'd really rather not have to do a factory reset, was just wondering if I could get some help. Thanks! I'm hoping it goes away on its own, but I doubt it will. Will update if it does though. Edit: I have also noticed the texts I receive dont vibrate or make noise, which is also annoying. Edit: Problem has seemed to stop... So bizarre. Edit: Problem is back. Great. Seems like the messages are actually not sending now too. Edit: Now its working fine again, what is going on?
