Yes
Use an iPod touch with the iPod dock.
dock connector cable
Yes, they all use the same 30 pin dock connector, the only one you can't use is the iPod Shuffle charger because it's completely different as it uses the headphone port to charge.
yes. but it depends on the docking station, if the cord plugs into the headphone slot then it wont charge the ipod it will eat ur battery and it will die in 5 minutes, but if the docking station plugs into the charging slot then it will charge :) but if u plug in ur ipod to charge it and play music and it dosent play then u may have the same problem as me :S
Well it depends what you would use your iPod for. If it's only going to be used for listening to music, I would just get an ordinary iPod. Although, if you want to download games and access sites like Facebook, Hotmail and Myspace over your iPod, then I would buy an iPod touch.
No, you do not have to pay to use Safari on the iPod Touch.
no,you can use ipod,ipod touch,or iphone.you have to buy nike+ ipod sport kit if you use ipod,you just have to buy the sensor if you use ipod touch or iphone
No. You can only use the app store that is provided to you on the ipod touch.
U have to disconnect the phone service and then u can use it as an ipod touch.
No. Ipod touch is only an ipod touch, you cannot use it as mobile phone. Iphone is better
Yes, but you won't be able to use Multitasking or make a background for your apps. Folders and the stylish new dock are pretty neat, though.
No, you don't 'need' Wi-Fi to use your iPod Touch. Your internet provider does not affect anything about your iPod Touch at any time. You can use the iPod Touch without Wi-Fi access.
