i have downloaded the .RAR file to make thumbnail into full screen picture while someone calls but cant find it on my phone and dont know how to install or run this file on the phone.
note: i use nokia 6630
Im not sure if i have got this right but i think the .rar file is a compressed PC file that you may need to uncompress first on your PC. its like a .zip file. inside you may find the program you want.
This is the format most downloads are in other than from comercial sites.
