This year, it's estimated 12% will have used cell phones to buy their holiday gifts, while more will have used cell phones to price compare, get recommendations from friends, find coupons, directions, and play games while waiting in long holiday lines, according to consumer reports.

Smart phones offer tons of ways to improve your shopping experience, and with Black Friday ahead, you may want one to give you an edge over other deal hunters, so you know when a store is opening early, which will have the best price, and can call to see if they still have that hot gift in stock. If you've used cell phones last year to improved holiday shopping success, or if you want to try it this year, here are some great used cell phones (a great price for the bargain hunter!) to get you started:

A refurbished Blackberry 8530 from Sprint is a great phone for organizing your holiday lists. Blackberries, which have long since stopped being a business-centered phone, offer great apps to help you play games, find deals, and manage your holiday shopping. If you've never used cell phones for more than talking, a Blackberry is a great, easy-to-use introduction.

A refurbished Blackberry Storm 2 from Verizon is a great choice for people who want a fancy phone with a decent camera (if you've ever used cell phones to remind yourself what you want, you know a camera is a great tool). The Blackberry Storm 2 is leap above the original Blackberry Storm, fulfilling people's hopes for a Blackberry touchscreen.

The Apple iPhone, from AT&T (but also a leader among unlocked cell phones), is one of the most popular among used cell phones. It's got tons of great consumer-oriented apps, is user friendly, and is great for the trendsetter on your list. Thanks to the great pricing of used cell phones, you can get it at a discount, or new, from Cellular Trendz.
