    you only need to give IMEI when your are newly activating a data plan. You can still call and give it to them but it will work fine without calling them

    oh i thought they would have to cause that is what my firend had to do when i sold him my old 3G which makes sense cause he did not have a data plan before getting the iphone.

    What would someone that buys my 3g have to do if they have no sim card nor data plan?

    If they already have AT&T, then they just need to insert their sim into the iPhone and call AT&T to update imei and add the data plan. If they are starting new service then best bet is to set up new acct @ an AT&T store and they'll do the rest. Good luck
