@kinextions: You may have to pay an activation fee. However, what you need to be watchful for is it is not reported as stolen or lost. To do this, you should be able to ask the seller for the ESN of the phone and then call Sprint to have them check if it is clean.

@MrOuija36: I can never remember because I do not use GMail on my device, but there are a couple of settings that need to be tweaked for that not to happen. Run a search for GMail and POP3 and you should be able to find a couple of threads on the forums.
