i have an htc incredible on verizon. I text a lot and i have many "conversations" going. I have not downloaded any texting apps (i use whatever was stock). And this has happened to me several times. I open a conversation, respond to the new text in the convo, and the text is sent to a different person. that different person has always been one of the other conversations i've had going (this may or may not be a coincidence). i've set my phone to delete messages when they reach 200 per conversation. this really enrages me. it's put me in some embarrassing situations. so, obviously this problem does not have to do with 3rd party apps. I've read about this problem being on other networks and other phones. though, when i called verizon about it, they, of course, had never heard of the problem. Google NEEDS to address this ASAP. if anyone has remedied the problem, please post!
