I *might* be having a shorter wifi range - but i also turned off (again - not sure who turned it back on) the router that was extending my network at about the same time. We have a lot of metal stubs in our house, and range is ALWAYS an issue with anything.
The only other thing driving me crazy is the frequency of the crashes in Safari - which however, have been going on since 2.2.1 (??). I need to do a restore before i can get it replaced.....
For some reason Music keeps crashing for me. At least once a day. And I know this isn't a bug, but double-tapping the home button no longer comes up with that cool blue window, but now just takes you to the Music app. Very annoying when youdecide you want to listen to music while you are in the middle of doing something in another app.
Maybe it's just for me, but youtube.com FAILS since i upgraded. It takes forever to load a short video, yet other load fast. I'm pretty sure it's not the router.
I've been on the road all week and used it a lot in many different (and new) settings and have had no problems with wi-fi, music, Safari, Skype, or a few simple games.
No real problem with wifi only need to boot iPod if wifi setting was turned off. Went to apple store to fix my YouTube app problem they fixed the problem but when i synced the iPod now I can't use YouTube app again.
