I'm not the first to post this on here but many people still don't know about it. It's not going to give you fastboot back but it will give you root without having to do the guide at http://androidforums.com/ally-all-things-root/263285-guide-froyo-2-2-1-root-users.html
SuperOneClick V1.9.1 is located on XDA at [APP]SuperOneClick v1.6.3 (Root, Unroot, Enable Non-Market App, Get UNLOCK code) - xda-developers
You need to read and follow the instructions on that page, and if it helps consider donating to the author of SuperOneClick.
Again at least three others have posted info about this program here and the thread easy way to root froyo that wroked for me touches on it but doesn't link to where to get it.
A thread tooting it as a one click (well almost one
click)root method for Ally with OTA or LGMU froyo doesn't currently exist on the Ally forum so here you go.
**update** SOC now supports the Gingerbreak exploit to root.
