Can I activate my iphone 3gs with virgin mobile?

I have an iphone 3gs 16gb phone and i want to activate it with virgin mobile. I want to transfer my account to the iphone 3gs. I mean they now support iphone 4.Is it possible?

Nah. Since virgin mobile is cdma, they don't use sim cards and virgin mobile requires you to buy their own cell phones. You can't bring your own. Virgin mobile USA right?

Not possible.
Virgin Mobile is a CDMA network running off of Sprint's towers.
an iPhone 3GS is a GSM phone.

You call virgin no sh! T

Nope
They don't take phones from other carriers
