If you paid for a 3rd generation but ended up with a 2nd generation, and you know for sure, go back to where you bought it with your receipt and all iPod accessories and iPod that came with it in the box and tell the return center that you want a 3rd generation, and not a 2nd generation.
they do for you
no...
2G
Any iPod Touch 2G case WILL fit the 3G. I've purchased two myself.
iPhone/iPod Touch/iPad iPhone: 1G, 2G, 3G, 3GS, 4 iPod Touch: 1G, 2G, 3G iPad
if you meen Ipod Touch 2G upgrading to 3G it is Bluetooth and the Search Page! if you meen Ipod Touch 2G and the new Ipod Touch 3G it is the 64gb and voice control!
Yes by about 1-2 seconds.
Yes
no only ipod touch 2g and 3g have built in internal speakers
Sadly, no i tried to use 3g or 1g firmware on my ipod touch 2g and it didn't work. You have to have the exact firmware file. Like if you have an ipod touch 1g with 2.2.1 firmware you have to have the file made for a 1g itouch that has 2.2.1 firmware
yes i believe so
4g is the best (it isn't even related to the question!) there both nearly the same but the 3g do have a wall paper after you unlock the ipod touch
