Hi, Everyone I know with a 4S is having dropouts with their phones and there seems to be very little discussion about this on the forums ... does anyone else have a situation that the phone seems to lose (dropout) data coverage yet retain voice, then drop voice and reconnect to the cellular network? Has anyone found a fix? I'm running SignalAlert overnight at the moment and even sitting in the cradle with 5 bars of real good (8Mbit/sec download speed) i've had 3 dropouts overnight. Is it specific to Telstra and Vodafone (Australia)? Anyone else seeing this? Anyone had a fix?
