At home on my iPhone 4 I would get 3-4 bars 24/7. Moved to a 4S and now I get ZERO for a time. Then it jumps to 4 bars for a while. Then 1 then 0 and so on. I send text messages and get more failed messages from home in a day then I had on my iPhone 4 in 3 months. Anybody else with worse reception then on their iPhone 4?
