I have installer 2.63 on my phone. I need to upgrade to 3.1 so I can connect to itunes 7.4.2 without the reboot loop. How do I update to the new version? I go to the update tab in the installer and nothing happens. The apptapp installer doesnt work if the installer is already on the phone. If there was a 3.1 pxl file out there it would be easy, but I cant find one. The PXL repository has up to version 2.63. Any ideas?

2.63 is the latest one, 3.1 and .92 are the installer versions. The problem happens if you use an old installer read
