Hey,
So this is what I did.
I go to blackberry desktop manager, click application loader, add a .ALX, and it says "This application is not compatible with your device and cannot be loaded."

I have the latest blackberry desktop manager, and the Blackberry 8800. Thanks!

Is the theme you downloaded made for your device?

Themes are device specific. There is flexibility with 83xx and 88xx phones.

Someone,
Please change your profile to 8800.

Someone and Jo12345,
You should be able to load any 83xx and 88xx themes unless noted differently. Your devices are the exception. Most devices only accept themes for that device.

1: What model BlackBerry do you have
2: How are you trying to load themes
3: Are you SURE that the themes are specifically for your model of BlackBerry

not to thread jack but I am having problems with seeing my themes. I can load them fine with the bb manager but I don't see half of the ones I loaded up (I did a google theme search for my model). Out of the 6/7 I downloaded (various sites) only 2 worked (appeared on the theme list). Anyone know why? On the manager it said there was about 27 MB of space.
