Mobile phone files locked

[jpatto]

I was hoping to find an answer here but havent so decided to post this as someone might know.

Have a SPV C550 im trying to edit some of the items on the phone (for example a picture) i try to copy it over to my PC in order to change it and copy it back but i get an error access is denied etc. This happens for majority of the files in any location.

Anyone know how to remove this protection or point me somewhere helpful or another utility that allows me to modify the file?

Thanks
