I've had my first smartphone, a Droid 1 for two years now and my contract is finally up in 2 days. For months I have lusted after the Galaxy SIII and it is now within my grasp! The question I have is: which carrier should I go with, and for what reasons? I currently am a Verizon customer but am willing to look elsewhere; I liked the look of the Sprint unlimited data but have been reading a bit about how their network isn't very good and may be slow to roll out 4G LTE everywhere. I'm in the Lehigh Valley (Allentown) area of Pennsylvania - if that matters. I'm shopping on Wirefly/Cellular Choices because I used them for years to get other phones but are there any other, better deals for the S3 out there? I am thinking of calling Verizon anyway, just to see if I can squeeze a good deal out of Customer Retention. All help and advice is appreciated!
