It is recommended that you all hold off jailbreaking 2.1. There are many issues that dev team is working through. A jailbreak isn’t quite enough.
Many apps are not yet stable. Categories will not work because we cannot launch one app from another at this time. Cydia is not yet stable. I recommend you wait a day or two still.
Dev Team released QuickPwn and PwnageTool for firmware 2.1 (2g firmware, 3g firmware). It doesn't work with new iPod yet. Mac OS versions only for now.
Theiphoneblog just published first screenshots of the new iPhones firmware 2.1.
Running 2.1 (5F136) now, and here’s what we’re noticing: WiFi works fine (tried on Apple and Linksys routers). New icons for connection type (3G/Edge) in the top bar. New blue filled and half-filled dots to describe state of video and podcasts (watched/listened to). Genius Playlists don’t seem to work as well as iTunes 8, at least for me, with lots of songs coming back as “not related”.
After installing iTunes 8 for Windows, some users may see a blue screen error message when connecting iPhone or iPod to a Windows Vista computer. In some cases, the computer may immediately restart when connecting iPhone or iPod to the computer.
