Unlocking Iphone 3GS.

[brianelmer]

I have inherited an Iphone 3 GS from a relative but it is locked to Orange.My question is ,is it better to get a factory un lock for which I have been quoted around £45 or a non permanent unlock at about £15.What are the downsides of a non permanent unlock? Also I have been asked what software it is running on,how do I find this out?

What's the baseband on the 3GS

To find out software versions go into Settings>General>About.... it'll be next to "Version" and "Modem Firmware."
