So, I've never heard someone up here say, "Gee Wiz, I get great coverage and customer service from AT&T!" I have been with ACS for a number of years, and always get awesome customer service at the Eagle River store. The coverage seems to be great in comparison to my wifes's GCI.
I currently have the Casio ROK phone, necessary after dunking the RAZOR in the Kenai last year, and really like the waterproof/shockproof aspects, but I really find that I need to be connected to my emails better than I currently am.
I have also been an avid apple user for awhile, and find their apps very useful and fun on my iTouch.
I'm not sold on the Android. My dad and sister have one, and they have had a bunch of issues with missed calls, and not so friendly operating instructions.
