I have a Motorola V235 and it has 10MB internal memory and i'm running out of space. What i want is to delete files that came with the mobile and they are blocked, i can't delete them just like normal files. I have tried many programs like Motorola Phone Tools and some others, but they can't see the files that came with the mobile phone. That's why i am looking for help. I want to delete the files that came with the mobile phone and are blocked, things like sound files and images. Please help me. Recommending programs or writing links will help. Writing the detailed solution will help a lot more.
I want to make it clear: I want to delete files in my mobile phone, those files came with it, the files are blocked (the phone does not allow me to delete it), i know it is possible to delete them.

Thanks a lot!

Paul
