Sloooooooooooooow
50 minutes into the iOS4 upgrade and the green bar is under the K in the backup phase. I'm using a 8GB 3G iPhone with only a few hundred MBs of space used. No music, probably 5 TXTs, ~15 pictures, but 4 pages of apps. I don't think it has to do with the content because I don't think I'm even using 1GB of space. And of course, as soon as I posted this the backup finished and now it's onto the restore stage. I'm on a Win7 x64 PC with Intel Core2Quad Q9400 and 4GB RAM, so it's not the machine either.
