Trade in phone

[Evo4g]

Does sprint wipe the phone clean of your info when trading in? I am going to trade in the evo, but want to make sure my stored CC numbers and personal info get wiped from the device.

Does sprint wipe the phone clean of your info when trading in? I am going to trade in the evo, but want to make sure my stored CC numbers and personal info get wiped from the device.

Why not wipe it yourself?
