My company uses VZW BBs (no SIM req'd), and I have a user who has an AT&T BB (SIM installed)... He's asking me how to wipe the SIM card so when he returns the AT&T BB, it doesn't have his info on it. Is the adv. options wipe sufficient enough to clear the SIM of his contacts? I have a SIM card which only benefits me for International use...UGH!
