I'm on Sprint right now and have the HTC EVO 4G LTE as my personal phone, but my company is getting me a BB and I'm considering AT&T. I had AT&T about 8 years ago and they were terrible. I had dropped calls all of the time, so I want to know how your experience has been in the MD/DC/VA area with AT&T? Also, do you have dropped calls or poor reception making calls from your basement (as that is where my office is when I work from home)? Thanks!
