Recently I posted the news of unlocking the iphone, and as per me it was kind of complicated process. Well so here is an alternate method using the turbosim. The few things you may require (as stated by the site ) will be :
- Jailbreak (link applicable for Windows users)
- SSH enabled (link applicable for Windows users)
- iPhone activated using your own AT&T SIM’s token (DVD Jon’s PhoneActSrv will not work!)
(eg. iASign method using AT&T’s ICCID. Link applicable for Windows users)
- You have the Turbo SIM – Blank Version available from Bladox or Votech
