iPhone 4 (Rogers)
I am selling a black, 16 GB, iPhone 4 that is locked to Rogers.
The phone is a warranty replacement I received from an Apple Store. Thus it is like new, being only a couple months old at most, but Apple only warranties replacements for 30 Days.
The device is locked to Rogers, but if you are a Rogers customer it can be officially unlocked by them for $50 I believe, and of course there are unofficial methods as well. One thing to note, the phone has never been jailbroken, and is running the latest version of iOS.
