So I recently ditched my iphone and picked up a refurbished Skyrocket. I love it except there are a few problems with texting. 1) My friends have been saying I send double or triple texts occasionally 2) When I send texts, sometimes it just says "Sending..." and never switches over to the time signature. Usually it does switch to the time signature and works fine. The "Message Sent" popup does almost always show up, no matter if it says "Sending..." or switches to the date. People usually respond to this type of message, but I can never tell if its been sent or not, which is a problem. 3) A couple people have received between 2-35 older text messages from me at once (they've sent me screenshots of things I sent and they responded to weeks or days ago). To note: I am running the SMS popup app (although the problems had cropped up before I installed it i think). Any ideas? AT&T was very unhelpful.
