YES!  I have been having the same problem since January 2012.  I've had my phone and AT&T service for two years with no problems at all.  And then, as of a few months ago, my calls are dropping like crazy.  I get one bar while inside, two if I'm lucky.  My calls not only are dropped, but my reception is bad as well.  If I'm on a call, either I can't hear all that is being said or they can't hear me.  I thought it was a problem with my phone, but Apple checked it out and it's fine.  We switched out the SIM card, deleted all information on the phone and then reloaded it, etc.  There is nothing that indicates that it is my phone.  AT&T said that they were working on putting up a new tower in my area, but couldn't explain anything else.  I cannot wait for the new tower which won't be up until August.  My phone is essential to my business and I cannot keep dropping calls.  I am thinking of going with Verizon.  Can anyone offer any advise?
