So, our ATT phones have been acting up the past few months....our two
year contract is almost over. I really believe they reduce signal to
people about to expire their contracts. Then they can say it's the
phone, not the service. Then when you get a new phone they throttle
your signal back up. Amazing that it's been bad service for two
months, then I called yesterday and yelled at them for a hour and was
cancelling my service when the rep offered me $40/month off my bill
for three months. So I said OK. Now today, both of our phones are
working perfectly!

I have been told, by a valid source, that utility companies to
throttle down your signal when your contract is close to expiration!!
Notice how they always offer you an "early upgrade option" to get a
new phone. Something to think about.....
