My friend gave me a 8310 that was activated with AT&T when he used it, I have service with sprint, however, there is no SIM card in the phone, what type of SIM do I need and how do i need to go about unlocking it to receive sprint service.

Hi Matt and welcome to the Blackberry Forum
Sorry, but you can't, the Sprint network is CDMA, and the ATT Network is GSM.
If your friend made the pin release from ATT, you can connect the device (unlocking) on Tmobile for example.
