Both the unlocking and jailbreaking are done with software?
Depends on the phone. Some phones need a special SIM to unlock, others must be connected by cable to a PC with bluetooth turned off. Some phones all you need is an unlock code which is calculated using the IMEI, model number, carrier and an algorithm which generates the code [easier than it sounds].
Jailbreaking is done with software like quickpwn. ************************************************************************* ** List info, subscription management, list rules, archives, privacy ** ** policy, calmness, a member map, and more at http://www.cguys.org/ ** *************************************************************************
