Samsung Galaxy S II :: Downloading From File Hosting Sites

I tried researching (for two days) on every possible corner of the internet but I haven't had any luck! First, my Galaxy i9100 info: STOCK 2.3.4 Gingerbread XXKG1 (ROOTED) BASEBAND I9100XXKG1

So, here's the deal, I'm trying to download files from file sharing sites, mostly RAR's, I've tried downloading from MEGAUPLOAD, RAPIDSHARE, WUPLOAD, FILESERVE, FILESONIC. All I get is an HTM file if I just click, If I long click on the "download now" button and "Save Link" all I get is a BIN file. I've tried downloading on the STOCK browser, tried changing the useragent (about:useragent) to desktop. (This I don't think works, it's weird, I've also tried changing the useragent from the debug menu but the option isn't even there). I've tried downloading on the STOCK browser after installation of ASTRO file manager (ticking the allow download all files). I've tried downloading on Dolphin Browser HD (V.6.1.0) with the useragent changed to desktop and I either get a HTM file (sigle click) or a corrupted file (long, save link) I've tried using OPERA Mini (6.1) with the same results as on the STOCK browser.
