no
For the 3rd generation, there is one already built-in. For the 1st and 2nd, you can buy an external microphone.
To get voice control on your iPod touch you need to have the 3.0 software or later (for any generation of iPod Touch). You must also have an external microphone for the 1st and 2nd generation iPod Touches, since the 1st and 2nd generations do not have built-in microphones.
Speakers were introduced in the iPod Touch lineup with the 2nd generation iPod Touch. The 1st generation iPod Touch does not have an external speaker.
It is compatible with the IPod Touch 2nd Generation. It is not compatible with the IPod Touch 1st Generation.
Yes, the 1st generation iPod Touch does have Wi-Fi.
no the first is thicker and wider
Yes it is. Thus the name iPod TOUCH
Yes. As owner of the 1st generation, I have never came across an app that doesn't work on 1st generation iPod Touches. All apps downloaded from the App Store should work on the 1st generation as long as you have the correct iPhone OS. However some features within the apps may not work such as microphone input or bluetooth connectivity. This requires a 2nd or 3rd generation iPod Touch.
iBooks if available on 2nd, 3rd and 4th generation iPod touch with the iOS 4.0 update or higher. Since 1st generation does not support iOS 4, iBooks is not supported for 1st generation iPod touch.
the ipod touch 1st generation and the second generation
The 3rd generation iPod Touch is the latest generation of iPod Touch, and basically means that it is the 3rd time around Apple has improved their iPod Touch (1st gen being the first they released).
The iPod touch 3g is the newest model! (=
