How to unlock iPhone 3GS already jailbroken?

[ptolomy_was_right]

Hi -

I have an iPhone 3GS 16GB bought from a friend but it's locked to the 02 Network - I want to use my T-Mobile SIM card in it - it has been jailbroken, so phone content/apps are accessible with no SIM/wrong SIM, and it has the app Cydia which is supposed to unlock it... but you must be connected to the web either via wifi or mobile data. Problem: won't connect to wifi network, but is this because I am trying with no SIM in? Do I need to get an 02 SIM from somewhere, just to connect to wifi in order to use the Cydia app? Would an alternative be to use a friend's 02 SIM to connect to the Web to do it?

Firmware version: 4.2.1
Modem Firmware: 05.15.04

Any help appreciated, thanks

I am not having much knowledge about it, since I am trying to Unlocking permits the phone on supplementary haulers meaning extra phones sold, meaning more money for Apple. And there are almost certainly even a little out there who wouldn't buy the phone if it couldn't be jailbroken. Reports from those who have installed the software declare that the phone does indeed permit for non-App Store applications to be installed. In fact, the ultrasn0w unlocking software also works all right, despite the fact that some report that unlocking the phone somehow affects the performance of Wi-Fi. I think that you are facing the same issue.
