gHack's have posted download links on their site for Windows XP Service Pack 3 which is scheduled for release to the public tomorrow, April 29th.
If you are keen to get XP SP 3 then jump the gun and download it now before the servers get overloaded on 29th.
I've just started downloading the 316mb upgrade and the speed is not bad on my Thai TOT narrowband link. I'm getting about 28kb/s. Just 3 hours to go...... Just enough time for a run to the Buffalo Bar for a quickie.
