From my understanding you cant update it, you have to buy the next generation, its apples way of raking in loads of money, hope that helped.
2G means Second Generation. So it is a Second Generation iTouch.
No, You'd probably have to buy a new one
No there is not. As of now if you would like an iTouch that looks like a second generation iTouch you should get a second generation iTouch.
The most recent iTouch is the iTouch 3rd generation, which is the newest one available.
Well, the 2nd generation version is thinner, and that's about it!
Apple has not revealed any plans for when the next update comes.
The itouch 2nd generation
Now there is the iTouch 4th generation with a camera and more improved things!
Upgrade it to the newest operating system and then it should appear. You can upgrade by hooking the iTouch up to iTunes and pressing update.
mmm no
3.0 just came out. If your a developer you can get it now. But for everyone else it ships this summer as a free update for iphone and iphone 3G users. the iTouch update will cost $9.95 and will come out at the same time.
Redownload the app, restart your itouch. Update. Most bugs and crash issues will be fixed in an upcoming update.
