    Call the original service provider that the phone is for and ask if its lost or stolen

    well first off, GSM phones dont have ESN's, they use IMEI's. in north america, cell carriers dont block stolen IMEI's the way CDMA providers block ESN's. however, the PIN for a blackberry can be blocked by RIM. so go ahead and call AT&T and ask them if the PIN and IMEI are clear.

    its irrelevant what network hes on. the Bold is a GSM only device so he would have to call them either way to verify the IMEI and PIN are clear. and he clearly stated in his first post that the current user is using it on t-mobile and he needs it for at&t. both of them are GSM only carriers.

    The IMEI is the serial number for the device but isn't used to activate the
    phone such as the ESN is for CDMA. All that activates the phone is the sim
    card.

    However as stated above, the IMEI could be blocked by RIM. The OP just
    needs to call AT&T and they'll be able to verify it. Simple as that.

    I said gsm phones don't have ESN's, not that they don't have serial numbers. Gsm phones have IMEI's for serial numbers and don't need to be programmed like a CDMA phone does.

    Yes you can use his phone because the Bold was sold in an unlocked version and the ATT version which means if he is using it on tmobile then yes it should work on ATT. Yes GSM phones have serial number. No nothing has to be cleared for you to use a gsm phone normally. In this case it does because RIM takes the extra precautions that the carriers don't. I would be slightly weary though if this guy is telling you not to worry about serial numbers. That sounds sketchy to me!
