I seem to be having an issue with calls, iMessages, and texts In my area (Sheboygan, Wi.). A family member has been having their iPhone constantly go to "Searching..." And when they have service iMessages sometimes fail. A friend of mine with an S3 has been having problems sending text messages, and another friend with an AT&T device called me and he dropped the call In a place that usually has 2-3 bars. The tech on twitter says they're doing "tower work" in the area. I drive past 2 AT&T towers regularly and haven't noticed trucks, new panels, or any activity.
