I am looking into creating theme's for my pearl. I was wondering if there is any info I should know before putting one that I make on to my BB.

I am using as of now Plazmic CDK 4.2.2 for BlackBerry, the theme editor it contains.

Anyone know if I load a theme will it kill my Pearl making it spontaneously combust into a ball of fire and doom?

If you're unsure the theme you have made is 'safe' for your phone, I'd recommend doing a backup prior to loading it to the device. That way if it does go up in smoke, you can always revert to your backup.

I usually do a back up every few weeks or whenever I make significant changes to my device. That way, if something does happen, you don't lose anything important.

that actually would be a great youtube video! but on a more serious side just backup your device and you should be fine.

let us know know it goes - I would like to do the same thing!
