You could visit a McDonalds or Starbucks, as they often have free wifi.

WiFi and 3G

The 1,2,3 gen don't have a camera but the 4 gen does I think and yes they all have Internet if you have wifi or I think Bluetooth but I'm not sure on Bluetooth

Wifi, 4G, and Bluetooth.
wifi is a wap (wireless access point (used for internet)) bluetooth is a data conecction (used 4 sending data)
You cant get free wifi for your ipod touch. You have to get a wifi router.
Yes.
Bluetooth and WiFi are the two most dominant wireless technologies to choose from for personal connection. (I'll assume you PDA is not a cellular phone) If you don't want to use WiFi, then Bluetooth is really your only option. You can setup your Computer which also must have Bluetooth as a Bluetooth modem. You can then connect from your PDA to your Computer via the Bluetooth connection and to the internet. This however will be significantly slower than WiFi and the distance you can travel form your computer will be short.
