I do not have my Droid X yet, but I have been reading the forums to be prepared for rooting and installing Froyo, if it is not out by the time I get the Droid X in the mail, 9/21.
I was on MDW and found a new Froyo release from the Master of Leaked Releases, P3Droid. I am posting the link to MDW for everyone at DF to enjoy. I can not wait to read the feedback.
