unlock iphone 3gs

post #1 of 16
Thread Starter 
Hi guys,
Just bought a iphone 3gs from ebay, its locked to orange, and i wanna be with o2.

I need to unlock it but, because its off ebay i have no idea what software is on it and i can't even star the phone up because i dont have an orange sim.

So what should my next steps be if i want to unlock the phone to use a o2 sim?

Do i go to the shop get an o2 sim stick it in the jailbreak it with software or do i need an orange sim to jailbreak it?

Also, what software is best to use and the most easy as i am iphone noob.

go to jailbreakme.com and you just slide the slider on screen. Note you need an original SIM to unlock the phone (so if it was locked to orange any orange sim should unlock it) then you simply reboot and swap sims.

You can get SIM's for pence from local markets or use a friends just to unlock the phone.

As far as im aware (only had an iphone for 2 weeks) you have to jailbreak it to unlock it unless the phone was bought originally unlocked.

You'd have to Jailbreak it, then install ultrasn0w via Cydia, then unlock it using that.

That is, of course, dependant on firmware and baseband of the phone itself, if the baseband is the newest, then you are stuck on Orange unless you use redsn0w to create a custom .ipsw and flash it to the iPad baseband, which causes problems with GPS and 3G (As I've experienced), but is unlockable.

That would also void your warranty in a very obvious way, as it can never be flashed back, or downgraded.

To be honest, there is no "Fixed method" as per say for Jailbreaking or unlocking the iPhone. It is 100% dependant on the iPhone Firmware and Baseband, with each different one, there is a different way you must unlock.

The best thing you can do is have a search online, and on the phone goto Settings > General > About, and do some googling on how to Unlock your phone on it's current Firmware, and how to unlock it on it's baseband.

Sadly there is no "One thing does all" soloution with iPhones, it's is dependant on the iPhone itself. It's could be easy, or it could be hard, or it could be impossible.
