How much more expensive would switching to Verizon be from T-Mobile?

Switch from Sprint to Verizon at Best Buy?

• I got the iPhone 4s on January with Sprint and my coverage is complete crap. Constant dropped calls, messages not being sent or getting to me late, suuuuper slow Internet. Even when Tmobile slowed me down for passing my 2 gigs that Internet was 5 times faster then what it is on sprint. So I'm gonna switch to Verizon cus I've tried a friends iPhone at my house who has Verizon and it just works a lot better. I don't care about paying the early termination fee cus it's better then paying $100 a month for another year and a half for pretty much an iPod. Can I go back to best buy and cancle my plan and get one with Verizon without having to buy another iPhone or switching numbers? And I got the geek squad protection from best buy too so can I just keep that for the same phone or is that canceled with the sprint plan?

• Answer:

  You cannot use your Sprint iPhone on Verizon. You will have to start service with Verizon (at Best Buy or Verizon or at any of the other Verizon authorized retailers), buy a new phone and have Verizon port your phone number. This will effectively end your Sprint service and trigger the early termination fee. Once the fee is paid, you will be able to sell your Sprint iPhone and its ESN will be clean.
