Just install ITunes for Windows 7 x64.
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 :)
Simply jailbreak your iPhone 3G or iPhone 3G and install Cycorder.

The iPhone 3G already have a camera that is capable of recording video. The inability to record video on the iPhone 3G by default is a software limitation rather than hardware limitation. To record video on an iPhone 3G, simply jailbreak your iPhone 3G and install Cycorder.
No. It can use your 3g
sync the iphone with itunes
Well, to install iTunes on your computer you don't have to use your iPhone. You just go to the Apple website, and search iTunes, and then you can just download it from there. If you want to sync your iPhone with iTunes to back up your content, you just sign in with your Apple ID (if you have an iPhone you should already have one), then plug in your iPhone and press sync.
If you are referring to an iTunes account, they can share. They do not need separate accounts.
