Hey all. So I'm pretty sick of AT&T and their data throttling. I stream a lot of sports games on my phone and after streaming 2-3 games, my phone is already at the limit and AT&T caps my UNLIMITED data. Thinking of moving over to Sprint. I currently have an iPhone 4 with AT&T. How easy is it to switch? As easy as calling to cancel my AT&T contract (which is up this month), then heading over to a Sprint store with my current iPhone 4? Whats the difference you've noticed in data speeds in NYC with Sprint over AT&T? Thanks for your time!
