I bought a Verizon Blackberry 9630 today, the seller said will it will work with all SIM cards. I am having trouble "unlocking" the phone from Verizon Network. What I have done is "manage connections" the change network to "2Gang3G" type the MEPDthing and I am still promted for a 8-10 digit KUP code. Which I believe is relative to my MEID or S/N. I called AT&T with no luck. I see there are paypal companies online that can sell me this code after i give them me MEID. Can I trust these guys? Where should I go next?
