One of the great things about running eBay's Developers Program is I get to see some really cool products in action.  Two particularly innovative products in the wireless arena are Receller and Unwired Buyer.

Receller allows a cell phone user with a built-in camera  to take a picture of an item and have it quickly listed on eBay by one of Receller's trained representatives.  Unwired Buyer will notify you via a phone call to your cell, landline or even SkypeIn number when an item is about to close on eBay.  You can use a phone keypad or Skype's dialpad to bid or buy the item. 

Now you can buy and sell on eBay without ever visiting the browser. Check them out!
