Can't use the Sprint phones on any other cellular service other than Sprint. You can always sell the Sprint phones through eBay or Craigslist to make it more affordable to switch to another carrier.
I have 4 phones. HTC Mogul, HTC Peral Touch Pro, Motorola Q 9c and a Nextel I-965 our existing i860.
contract expires in 4/10
HTC Mogul failed 5 times and they would only relaced w/a Mogul.
Bills always wrong,
Tookthe whole open by change in terms. neeed to get back up but ideally same phones or just some kunk to fill time for at least 2 phones.
