Yeah....I know how to do the design part. I'm looking for software to compile and save/export.
I'm a Blackberry Theme Designer and want to convert my BB Themes for iPhone.
To be honest I dont think one exists (not a good one anyway). As all themes work via Winterboard, its just a matter of having the right file system set up and most designers do it manually.
Even if one did, it would be pretty weak and would need constant updating since apple changes their file system constantly and designers are coming up with entirely new lockscreens and widgets on a daily basis.
