Should I stick with verizon or move to sprint?

I currently have verizon the coverage is good but I want to get the iPhone 5 I have the 4 with unlimited data its good but I'm getting tired of 3G it's slow. I seen sprint is the only carrier with truly unlimited data I hardly make phone calls but I'm a heavy data user and text once and a while if I upgrade from my line I lose my unlimited data. Which is what I don't want I live in the Los Angeles area do they have good coverage?

If i were you, i would stick with sprint, because, verizon is really slow and expensive, sprint is okay

Neither.cricket carries the iphone 5 and the bill is only $50 a month for unlimited talk, text, and data (or $60 if you want your mobile hotspot activated in addition to unlimited everything)

Verizon is a better network than Sprint, with both call quality and data speeds. The 4G/LTE is faster on Verizon, and so is the 3G network. Sprint is still building up their 4G network. It can be hit or miss in certain cities. If you pay full price for the Iphone 5, you can keep your unlimited plan, which would be amazing. Unlimited data on the fast LTE network of Verizon. It is slow on Sprint's network. I recommend you stay on Verizon. You could regret switching networks. If you are concerned about the price, you could possibly sell your Iphone 4. Personally, I would wait for the Iphone 5s that is coming out in a couple of months (Fall).
