Apple’s introduction of the iPhone 3GS led to a $100 price cut of the last generation iPhone 3G but now, you can pick one up even cheaper.

AT&T is offering a $20 $70 discount for the 8GB and 16GB iPhone 3G respectively. The only caveat being they’re refurbished models which tend to carry some sort of scuffs or scratches. Another downside to purchasing a refurbished iPhone 3G is the 90 day warranty instead of Apple’s standard 1 year coverage. However, if you’re fine with buying a slightly used model and looking for a good deal on the iPhone then go to your closest AT&T store or shop online.
