So i have a question, after installing 2.2 on my hero, everything was working fine, until now. im having problems with my text messages, they wont send under sprints network, if i put it in roaming then they send right away, but roaming has awefully slow (1x) network speeds, but if i put it back to the 3g network speeds of sprint then everytime i try to send a text it just swirls in circles (the little thing next to the message) and wont send. is this sprints network being down? or does this have to do with the 2.2 update? i dont think its sprint because my mom and sister arent having any problems with there phones from the same plan. but i tryed restarting many times, taking out and leaving out the battery, putting it in airplane mode and turning that back off to reset connection, iv tryed everything and cant get it to work, so idk what to do, and i dont understand why if it was a software problem with the 2.2 installation, why would they send in roaming but not on sprints network?
