RCMod 2.0 is, as usual, an upgrade (no data wipe required). I never tried upgrading directly from the stock ROM (only from RCMod 1.3), but other users did, and had some trouble with the data conversion. So if you're upgrading from the stock ROM, I advise you to upgrade to any version of RCMod 1.x first (or Wipe your phone, but that will delete all your apps and settings).
Please do a nand backup before you attempt to upgrade!
Updater: Starting from 2.0.10, the RCMod Updater app is included, and will do daily checks for new versions. I strongly suggest you use it to do your uprgades, to avoid breakage due to missed incrementals.FeaturesRCMod 2.x is built from the AOSP (Android Open Source Project) version 2 (codenamed
Eclair), with the necessary changes to work on the ONE's hardware and some minor optimizations (the current base version for RCMod 2 is AOSP 2.1r2). Some highlights:
2.0.3- Full basic Android applications stack (Contacts, Calendar, etc)

- New slider lock screen

- Includes HelixLauncher as an alternative to the regular Launcher (when you use Eclair for the first time, it'll ask you if you want to use Home or Helix)

All the fixes and features from previous versions of RCMod have been forward-ported. However, it hasn't had as much testing as RCMod 1, so there are probably some bugs left. Keep in mind this is a BETA release before complaining, but feel free to point out any problems you come across (before you do, just make sure it hasn't been mentioned before by someone else)
Please remember this is a full upgrade, so if you have the Google Apps installed you'll have to install them again after applying the update. You'll need the Eclair version of the Apps, which can be found here:
