If you buy a Verizon version and the 3rd party stores link it to your Verizon account, you will be charged an upgrade fee. Only way around it, is buying an unlocked phone from places like Samsung, Best Buy and swamping your SIM cards.
Just a bit nervous. UPS says scheduled delivery tomorrow but it it 2 day air. I hope it is delivered tomorrow but since origin scan is today, I don't know if I trust it.
If the phone is less then 90 days from purchase, it is locked to Verizon. It has to be on the Verizon network for that long before it will be automatically unlocked.
