Please can someone help me, ive just downloaded the android 2.3 system update for my desire hd and i cant send txts to anyone at all, when i try to send the screen goes back to the home screen and my signal then goes down to nothing. Ive tried downloading 3rd party messagig apps (ive currently got Handcent but ive also tried go sms) and it does the same. Anyone got any ideas what else i can do or try?
