Backflip root 

The Motorola Backflip is the latest phone to get rooted, and it's using the same exploit as was used on the Droid 2 and the Evo 4G. This makes things really interesting, as any root method that works across different models and manufacturers is a very welcome change. And we all should encourage the rooting of all Android phones on AT&T, even if only to uncripple them let them run the OS as designed.

The standard disclaimer that this breaks warranties, can brick your phone, and maybe even make your dog run away still stands.  If you decide that this is for you, hit the source link and have at it. []
