I don't know if this is a common issue, but I know it was common on the Droid 1s, because I spent a few hours on google today, reading old threads from last year. I was having issues with Handcent not sending MMS messages, the loading circle would just spin indefinitely, and the picture either wouldn't send, or would not be viewable by the recipient. I tried different Apps (Go SMS, ChompSMS, Handcent, even the STOCK one), and nothing worked. I unfroze messaging and messages, text messaging, and then it struck me..... You need the stock gallery app functional to add pictures. I'm not sure why, I'm thinking maybe when Handcent resizes it, it resizes it using features built into the Gallery? Anyway, it worked for me, I hope maybe this can save someone a few hours of guessing in the future.
