The BlackBerry Bold 9700 (Onyx) won’t officially be released on any particular carrier until some time next month, but you can secure yourself one of the hottest new smartphones before then… and you could get one for free. CrackBerry and Ringtone Expressions have partnered up for a pretty cool contest and the grand prize is worth over $700.

In a nutshell, you make a custom ringtone using the Ringtone Expressions application, the trial version of which is a free download, and then the maker of the winning ringtone will be awarded with a BlackBerry Bold 9700. This is factory unlocked, so you can have your choice of international carriers.

After making the ringtone, you’ll need to compose a Twitter or Facebook update in Ringtone Expressions, including the #CreateRingtonesWinABlackBerry hashtag in there (I didn’t know FB used hashtags) so that they can track the entries. The Bold 9700 sounds pretty sweet and free is even sweeter.

The contest (official page here) starts today and runs until November 3. Even if you don’t win the BlackBerry grand prize, you might be one of the ten finalists to win a $50 coupon to ShopCrackberry.com. If you’re more of an iPhone person, check out our Mophie Juice Pack Air giveaway instead, which ends this Wednesday.
