- Use it essentially as an iPod Touch (no phone service)
- Sell it
Unfortunately, I can’t use it as a backup phone since I’m also switching carriers — AT&T to Verizon — and the 3GS model is not cross-carrier compatible.
I don’t really have a need for another iPod, so I decided to sell it on the used market. But what’s it worth? A quick check with Gazelle.com surprised me. Even after the upgraded iPhone 4S announcement and release, my 3GS phone is STILL worth $120 — which means my net cost for the two-year old phone was not the original price of $199 — but only $79!
With this experience, I decided to bump up my order to the mid-level iPhone 4S 32GB at $299. I believe it will have a similarly strong resale value two years from now.
