slow download speeds please help!

[forceofnature]

My phone sometimes gets really slow download speeds when I download files from hotfile.com, etc. I never know when its going to be slow or fast, it is sporatic. Sometimes it takes hours to download a 100mb file or it stops halfway through and won't download. Loading sites are never a problem, its just downloading files

If it's just sometimes it's probably your carrier and not the phone
