iPhone After Factory Unlock will I loose my Jailbreak?

[dhlizard]

can u provide the cheapest O2 UK Factory unlocking service, REAL UNLOCKING ( no scam sites ) ?

thank you again

Expecting a particular forum member to know the "cheapest" aftermarket O2 unlocking service might be unrealistic - especially if that member lives in US instead of UK.

I recommend this thread - but I can't personally vouch for any particular vendor, it's just members sharing their experiences.

Remember, newest info on last pages of thread

Here is a list from JailbreakQA of vendors said to be reliable - although I have no idea of cost or if the can do O2 phones

This site is well know for solid unlocking service.
