Updated to 9.2.7 firmware

SMS messaging was working perfectly with 9.0.5 but now it doesn't work. It seems to be adding 1555 to the numbers because I get an error report back from the message center telling me that my message failed with 1555 then the number of the person I sent the message to. Anyone got any ideas of how to get rid of the 1555?

sometime i got trouble as sms sending stop at 90% #_# just happened today, so i must rs to fix it (but who know when will it happen again) and one other that camera work not properly and even too slow to take a shot >"<. Hope that next fw would deal perfectly with these concern #_#
