I recently got one of those Sprint pebbles that was sent even though i did not request. i finally set it up after nearly 1 hr of fighting with it. I was wondering:
1. How is this different that Sprint wifi calling ?
2. Can other sprint users outside of my house piggyback off this pebble ?
3. If I stop using the pebble after a few months, do I need to pay the $70 or is the $70 only apply if you never initially set it up ?
