I have a iPhone 2g that I brought over a year ago.
It is unlocked jailbreaked at 1.1.4 and is working fine.
I used ziphone at the time...
I have been reading and I see if I upgrade via itunes and unlock it will be fine at 2.1.1 (As it is a 2g the baseband does not get updated).
Is it a case of upgrading for the sake of it, or is it worth it???
I would need to restore it for repair if required??
Any advice on this, I hear some people had issues with slow downs with 2.0?
