As we known, when download file at share file sites such as rapidshare.com depositfiles.com megaupload.com... as a visitor or a free member, we are limited!
We may only download 3 to 5 files per day per IP or sometime we cannot download because the sites banned our country's IP.
This TUT helps you resolve that problem. Fake IP!
