I haven't received it yet, I picked up a 4GB (always wanted one) off eBay last week from a reputable seller offering a 30 day returns policy, so hopefully it'll be in the same condition and working order that they've described. I have an iPhone 4 but plan on using this as a work phone.
I can't wait to receive it, no other iPhone has come close to making me feel the same way I did when I unboxed my original 2G!
