[triniiphone]

If i sold the iphone 4 with the sim it came with, when the buyer activates it will my 3g stop working and theyll have my number? or do i need to remove the sim b4 i sell it?

You will want to remove the SIM card from the phone.

What he said.

A SIM cannot be activated twice. It's sorta like trying to strike a match again once you already burned it one time.
