    I have a few month old unrooted G2 Touch/ HTC hero with T mobile UK.. Its been losing signal a lot recently. I've been searching networks, then tapping on T-mobile and getting it back. But now whenever I start dialing a number it stops me with the message 'Connection problem or invalid MMI code'.

    Anyone know what this means? I've tried turning my phone off and on, and taking the battery out and putting it back in, as well as doing the same with my sim card. sometimes the phone works fine but today in particular its really playing up.
