Unless you have a mobile phone plan that supports Twitter, then yes, Twitter will charge you money.
Echofon* It's basically a Twitter app for iPhone or iTouch
u can charge your itouch anywhere that has a USB. an ihome can charge it and an xbox360 can as well.
Try a Belkin adapter.
No. There is no charge at all Twitter is free
You probably need to give it more time to charge.
No, Twitter is a free service.
It's possibly just a glitch. Try uninstalling and reinstalling the app.

No. You can connect to a wireless router free of charge using the iPod Touch.
It's basically just an application you can use if you are tweeting somewhere else. (basically not from your computer/laptop) It's nothing special. I think most people use that if they are on Twitter on iPhone or iTouch but idk.
No a Twitter account is free just like Facebook and MySpace
Either way would be ok, but when you have it off it charges faster.
