When I had SE T630 I used the CodeProject Theme made by Chris and Jeremy.
Couple of days back I brought a smartphone, Nokia 3230 and so I thought it would a good idea to make a theme for Series 60 smart phones.
1. You need to download the zip file and extract the sis file.
2. Using Nokia PC Suite install the sis file and follow the Instruction.
1. Series 60 Theme Studio (Downloadable from nokia forurm)
2. Adobe Photoshop 6.0
Is it secure or not secure?
If you do not trust if the sis file is good or bad. Download sisextractor and extract the content of the sis file.
You will see a couple of files, a .mbm file and a .skn file. Both are non-executable.
It should work in all Series 60 phones like 7650, 3660, 3650, 6600, 3230 but i have tested it only on 6600 and 3230. Please leave a note if it worked in other models
