ok, for some odd reason this week my phone gradually lost service...there's nothing wrong w/ it and i havent messed w/ any network connection stuff, but i haven't had more than 3 bars in almost a week. i have alltel and have contacted them but they gave me no help and just said it's b/c i live close to the airport, even though b4 this week i have always had full service in my room...anyways, anyone know what could be wrong?
