sprint pcs, used phones

[turnipmonster]

anyone have sprint and know anything about buying a used phone? most info I've found googling seems somewhat sketchy.

long story short, I lost my phone and need to get a new one, however I want the option of switching to an iphone in a few months so I don't want to sign a contract. cheapest phone in the sprint store is ~250, which is too much to pay for a phone I'm going to use for ~3 months.

I talked to cingular and they said def wait until the iphone comes out to switch.
