Selling 1st gen iphone is the tech deal of the century
I sold my year-old 1st gen iPhone for $430 on ebay just last week. I listed it as Unlockable and that they should let me know if they wanted it unlocked. The buyer did, so I unlocked in and shipped it out. Make sure and do a secure wipe!!
Previous poster questions ebay, but if you use PAYPAL I don't see how you can get scammed. I had the money transferred to my bank account prior to shipping!
So, I upgraded my phone for $200 and sold my old one for $430. What a deal. Also, Apple allows discounts on the 3G plans, so I get a 15% break as a government employee!!
