Over the past week or so, my iPhone has started having these period of time when it can't seem to connect to any network. I get the "Searching...." icon up in the upper left hand corner and it might do that for 5-10 minutes, then all the sudden everything starts working again. For a while, I blamed this on the recent slew of damaging hail storms that we had in the Oklahoma City area. But I am concerned that this might be something more. Is anyone else having this issue? ---- For the record- this is a 32 GB iPhone 3Gs and I am using it on AT&T's network in the greater Oklahoma City, Oklahoma area.
