iphone 4 unlock

[londonmystery]

Hi,

Have been asked by a friend to unlock their iPhone 4, 4.3.1 baseband 04.10.01.

Is it possible and if so how? Already have cydia installed.

Thanks for the help.

A quick google search revealed this: http://www.redmondpie.com/unlock-4.3.1-iphone-4-04.10.01-baseband-with-gevey-sim/

In short you need to buy a Gevey Sim and can't update to iOS5.
