Hello Jaxov, I am currently using a locked iPhone 3GS with baseband 05.14.02. I know that I will be able to unlock it using Ultrasn0w by updating its baseband to 06.15.00. However I don’t want to lose my GPS function as my jobs depend on it. Anyway, is there an available option to unlock my 3GS from O2 without losing GPS? Or can I install a standalone GPS after unlocking my iPhone using Ultrasn0w? How about Gevey SIM?

Unfortunately, you will not be able to unlock your iPhone 3GS using Gevey SIM Pro for the reason that iPhone 3GS does not use micro-SIM card.
But the good news is that, since your iPhone 3GS is locked to O2, you can request from your network service provider to unlock your iPhone 3GS for you. O2 people have capability to unlock your iPhone 3GS without jailbreaking or installing Ultrasn0w software carrier unlocking tool into your device. Therefore, you will be able to use any other SIM card of your choice, and best of all, you will not lose the GPS functionality of your device. To do that, all you have to do is fill up this O2 unlocking form and wait for their confirmation.
