thanks andy. i just dont understand why after two clean installs on 0820 and 0830, one phone worked perfectly and the other did not. in either case, i found a good work around. i am now using an aftermarket messaging app. what i love about it is it gives us alerts both audibly and in the notification bar whether data is enabled or not. on the stock messaging app, i could only get notification when data was enabled on my phone, as soon as data was disabled, the messages would appear but i wouldnt be alerted. now with the market sms program, i get instant notifications regardless of data enabled/disabled. so now i can leave data off all of the time and use wireless. my battery life is now excellent again. i only turn data on when away from wireless or sending or receiving a pic message.
