A CrackBerry.com forum member that goes by the name hastings has created a free BlackBerry Storm Theme called AppleBerry that looks pretty good for a free BlackBerry Theme. I haven’t had the chance to install AppleBerry on my BlackBerry Storm, however, CrackBerry Kevin has and has this to say:
The AppleBerry theme is SLICK. I installed it on my Storm and have been thoroughly impressed. Pretty much everything has been re-skinned, I love the message/calendar preview on the homescreen and “touch strip” is clever.
If you want to make your BlackBerry Storm kind of have that Mac look and feel check out the AppleBerry forum over on CrackBerry.com
