Heh, found that out just before you replied - went to the sprint store and he was like, "We only do PCS phones. You'd have to switch services to use this, but you're eligble for an upgraded phone."
"I'd have to start a new contract for that, though, right?"
"Yeah"
"What about just a new plan. Would that require a new contract, too?"
"Good question, let me check. Yes."
So, basically, sprint is forcing me to leave. I don't want to sign a new contract if I'm going to need to switch networks to use this phone. Guess I'll look into T-Mobile or something. Hopefully they can transfer my number over.
