No. But what I did yesterday when I updated to 2.2.1 is I downloaded and backed up my phone through aptbackup from cydia. Then I backed up my iphone in itunes, and upgraded using pwnage tool. Then I redownloaded aptbackup and clicked restore in the app, and it redownloaded all my jailbroken stuff automatically.
It's ok I got it. I'm using SBSettings, where you can toggle a window and choose airplane mode "on" or off". That way you don't have to close your current window to do it.
Thanks for the tip about backing up the apps. I'm going to get that now.
