Yes by about 1-2 seconds.
no...
they do for you
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
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
any apps for ipod touch 1g, 2g , and 3g will work and new ones
