I've been using the HTC Desire Z for almost a week now. I used to own a G1, then an iPhone and a Blackberry. Now im back on android, I'm loving it. But today my phone did something very odd and slightly disturbing. While it was in my pocket it decided to reset itself. Ok fair enough. But when It loaded, it said there was a new sim card installed. It asked me to check the time and date, it then wanted to link my facebook contacts to twitter (which it had done perfectly before already) so it tried to link people TWICE. But more importantly, it decided to resend some txt messages out to people AGAIN, without my permission. Not everyone, just 4 people out of my 10 contacts. My girlfriend got sent over 30 messages in a few minutes, all of which I had sent her over a few days. More odd was the fact that even messages she sent me in the first place were being sent back to her as if I had sent them. This is the only glitch/error/issue I've had with the phone and Its knocked me for six. Does anyone know about this? I don't want this happening again. I've just had to text people telling them to ignore all my re-sent messages.
