Motorola has posted a warning on their support forums today warning users not to proceed with the leaked froyo update that has been floating around for the past few weeks.
WARNING: Do NOT load the leaked 2.2 upgrade that has been floating around on the Internets. There is currently no upgrade path from that load to the official 2.2 load that will be released by early September. Unless you have some plan to flash your phone back to the current official load, you could be stuck on the leaked version.
If you have updated, don't worry the complete step by step guide was created by our friends at RootzWiki for just that situation. To return your Droid X back to a stocker, just follow the link here: RootzWiki - Droid X. If you have questions, hit us up in the Droid Hack section and we'll be sure to help out: Droid X Hacks
Did you happen to noticed the mention of early September for the official 2.2 update? Hmmmm.. How does September 6th sound for the new roll out?!
