Facebook deals made a quiet launch a few weeks ago with a lot of buzz surrounding how the largest social network would break into the group coupon model.

While the actual tool has not launched, we have uncovered a few more details around how it will work. The program will launch first in Atlanta, Austin, Dallas, San Diego and San Francisco, you can sign up for deals today and Facebook will alert you once they go live.

Deals will go beyond the mobile phone. Currently Facebook users can claim a deal through Facebook Places. With the different options for check-in deals, it will be interesting to see how Facebook expands upon this feature.

Deals will work with friends. Given the social nature of Facebook, this definitely doesn’t come as a surprise, but it does come as an added extra. Other deal sites like livingsocial allow users to forward a deal to friends in order to receive perks of their own. Since this can be tough, it will be interesting to see how Facebook taps into the social networking nature to create meaningful rewards.

Facebook deals will aslo be activated through a tab on a brand’s Facebook page. Apart from check-in deals alone, Facebook has created a dedicated tab to all deals so that a user can easily see offers for local businesses. Although the future enhancements of this are not clear, it is clear Facebook is ready to make this action easy and functional for users.

What are you thoughts on Facebook deals? Have you signed up? What will you expect to see when they finally go live?
