iPhone 4 Network

[iMore Question]

Hello,
I have an iphone 4 which uses gevey ultra sim having ios 5.1.1, bb: 04.10.01
Earlier when i was checking the sim lock on imei checker sites..it was showing sim lock: locked
now i see it displays: unlocked.
i have even used itools to check it, it says : Activation State: Activated

When i put my sim without the gevey sim, it says network unavailable.

Is there any solution for this?

That's because it isn't unlocked. The solution is to use the Gevey Sim. A device being activated doesn't mean that it's unlocked.
