Worked at last. Thanks guys. Downgrading my baseband from 6.15 to 5.13.04 did the trick. I have 3Gs and updated it to 6.1.3. with iTunes, JB with redsnow, install Cydia, Ultrasnow, then p0sixspwn for untethered JB. Found everything OK, except it was still SIM locked. Did the baseband downgrade with Redsnow and right away I could call out. Thanks again.

Nice article! Nowadays, many of the new arrival unlocking techniques are around there. We can't tell all the methods are fake or all are safe. Few techniques will give proper solution without bricking an iPhone. In my experience, Remote unlocking method is one of the safest unlocking solutions to unlock iPhones from carrier lock. It doesn't requires jailbreaking. Many of the providers offer this service with affordable price to open iPhone to work with all the GSM networks world-wide. We have to concentrate in winnowing unlocking method as well as unlocking provider. It’s very important. Before, getting unlocking service from any of the providers, you need to check whether they provide quality service, money-back guarantee, cost etc. Source : TheUnlockSpot.com
