I had a 1.0.2 firmware on my phone and just decided to upgrade. I did a upgrade to 1.1.1, Jailbreak and activation went fine. I started to encounter problems when I tried to download AppSnap installer - It took about 4 hours to download, but eventually it came down and worked. This is using wifi, with a network download speed of about 5mbps. It is so slow that I can't seem to get the BSD system downloaded to finish the unlocking procedure. I left it for about 11 hours today while I was at work and the download progress bar was only at about 20%. The installer never hangs or crashes, it just appears to be downloading so slowly.

But when I run Safari on the phone it appears to work fine. Sites are being rendered at about the speed that I would expect. I have tried when the phone is connected to a pc, and when not, without any difference.

Has anyone any ideas as to what could be going on here?
