No they do not. The iPod touch 4th generation has a completely different case then previous models.
they do for you
Where can I find iPod touch 1g rhinestone cases
No there is no such a thing of out keyboard cases for ipod touch. Nd pleas never jailbreak your ipod touch caus it makes it slower nd stupid
The IPod touch 4g has the most cases made for it because it is the most current IPod touch. You can find a good selection on both EBay and on Amazon.
There is no "regular" iPod touch, because they is a new one each year. Most iPods have different shapes, and cases for one will not fit another. Only the 2nd and 3rd generation iPods have the same physical shape.
No it does not because the Iphone is a lot bigger that the Ipod touch.
no
yes it is as long as the cetain accessorie will fit an ipod touch. iPod touches must have special cases, but things like headphones or iHomes will work with the iPod touch like any other iPod. BUT, some accessories won't work. Such as the iPod camera connector.
yes, you buy them separately
Any iPod Touch 2G case WILL fit the 3G. I've purchased two myself.
Snap on cases only protect the back of your iPod touch from getting scratched. They do not really protect against drops.
For the most part, yes. Most cases and headsets will work with both. However, the 3rd gen iPod Touch has some additional features not present in the 2nd gen iPod touch. The packaging for each accessory should indicate what versions of the iPod that accessory is compatible with.
