officially activating previously unlocked iphone

[h-man75]

Hi,

Quick question if anyone would be kind enough to humour a total n00b. I am considerin buying and unlocking a new UK 8GB iphone using ziphone and using it on UK Orange. When my orange contract runs out in a couple of months, I am considering changing to an official O2 iphone tariff. Is there any possibility of returning the phone to a state where I can plug it into itunes and activate it the "proper" way?

Many thanks in advance.

Yes, there are several ways to go back. One of the easiest is to simply restore from iTunes.

Be careful that you don't choose an unlock option that downgrades your bootloader, as that may limit your options in the future. (Apparently ZiPhone 2.4 does this by default, but earlier versions do not.) There are a couple of threads on this topic.
