I first had this problem with my TP2 three weeks ago. It all started with rebooting my phone, then for some reason it couldn't recognize my password anymore and I was locked out. Luckily I did a backup a week before, so I had to hard reset and run my sprite backup file.
But ever since backing up I've had a new problem every weekend since then. Now the phone is lagged by SMS texting it seems. Got the error "the message cannot be signed and or encrypted" when trying to send text. Have hard reset 5 times, backed up files selectively to try to weed out the problem to no avail. Rather than going into detail about this I'm starting my own thread lol. It has been driving me nuts for the past few weeks!
