HI, I've got an HTC desire and my carrier is Altell. I can't send or receive picture messages. I press download in the text but it just sits there and says downloading... or "sending" i've tried with wifi-3G on/off and nothing seems to work i've even tired this in the stock messaging app and handcent sms. However nothing seems to be working and my girlfriend and myself are VERY frustrated. does anyone have any ideas?
