I just got done updating my ROM on my X30. It was great, a peice of cake and definitely worth it!
Here's how:
Create a back up of your existing data
Download this from Dell
Unzip the download into a desktop folder.
Click the Setup icon in the folder.
Create the back up(I put it in a desktop dolfer also)
Then let it go... ... ... And you're done!
Oh, and now you have WMP 10! Its well worth it!
