yes you can just go to unlock att .com and after you process it you will be able to use it on any service !!
no, you dont. you can jailbreak your iphone and run it on tmobile's network, if you have a tmobile sim card. but on tmobile, you cant have 3g speeds, only 2g.
I would believe so, it can be difficult to unlock your iphone though but the iphone is exclusively at tmobile in Europe.
Yes it will, but it will not support 3G. It works on the Edge network just fine.
yes. However, it may or may not work on 3g because ATT and tmobile use different radio bands for their 3g networks
Yes, use PDAnet to connect it. To get PDAnet you will have to jailbreak your iphone.
If you just recently got a new iPhone 4, connect it to iTunes and iTunes will identify it as a new phone. If you have previously synced your iPhone 3G with that computer before, then iTunes should give you the option to sync the new iPhone with a backup from your latest iPhone 3G sync. When you do that, your files from your 3G will be transferred to your iPhone 4. Hope that helps :)
Of course, the iPhone 3G and/or the original iPhone will take any normal sim card; the 3G iPhone will take the 3G sim as well.
iPhone 3G S = iPhone 3G + Extra's
Connect to either WiFi or 3G and go to Safari. Start searching.

No there is not, iPod touches can not use 3G. Only wifi. Also you cant get a cable to connect them anyway.
