A shorter version of Cynergy's Windows Phone 7 eBay App video. Imagined, designed & developed by Cynergy in an impressive 131 days, the Windows Phone 7 eBay app lets you search, bid, and check auction activity on the go. In their WP7 review, The Chicago Sun Times said: "The eBay app is magnificent. The app doesn't come across as a mobile client. It looks like a slick little promotional video for the items you're browsing."
