Hey guys,
As it says above, I have a 3G 2.2.1 Out the box iphone.
I have jailbroken it using Quickpwn but I notice my transfers through wifi are quite slow and sluggish!
I have broadband which is quite quick in my opinion, but when I download large packages through my wifi connection in cydia, a 17MB file can take almost an hour.
It is actually quicker when I try downloading the same package with 3G. Although thats an expensive alternative and not an option for me.

Does anyone know why this is happening? Can anyone suggest a fix?

Thanking your replies in advance.
