Sprint Rules. They may be a little behind in the 4G war and upgrading their existing 3G network, but they have great customer service in my opinion and you kinda can't beat the Unlimited Data. And their pre-paid divisions such as Boost and VM are just as great. Again this is just my personal opinion. I as well used to have Verizon. They raped me with a $120/month bill for just one line! F*ck that! My girlfriend currently has an Android on AT&T with a 3GB data cap. That's fine if you don't use lots of data, which she doesn't. But me on the other hand, I use Spotify constantly. All my music is uploaded to "Google Play Music" cloud service, Netflix almost all the time for my kids and I have an Emit Media Server set up on my PC that I access all the times for my kids while we're in the car, or we're somewhere my children might find boring. Unlimited Data is an absolute must for me. I am currently on Boost and use 15+GB's/month. They have yet to say anything to me since implementing the new 2.5gb data cap (which really isn't a data cap, they just slow you down to 256k after 2.5gb). I've used over 10GB this month and i'm still @ full speed.
