yes, but not all iphone 4 apps are available on the iphone 3gs/3g/2g becuase they are too high resolution apps, or need a front facing camera.
you will have to jailbrake the phone ...
plug your iPod into your computer, click iTunes, then it should put your apps on there. Then plug in your iPhone, and it will automaticilly download.
I assume by apps you mean programs preloaded. The way you would tell that is get an iPhone that has no apps and look at the icons. Those icons are: calendar, photos, camera, YouTube, clock, maps, notes, stocks, calculator, settings, weather, safari, mail, app store, phone, messages, iPod, contacts, iTunes, (voice memos on OS 3.0). I do not have the iPhone 3Gs so if there are more I don't know them.
yes infact the iphone 3gs does have AIM (aol instant messenger) it works very good and to donwload it all you have to do is go to apps on the phone and type in AIM but usually it will cost no money and sometimes it will but it does tell you. to get an iphone 3gs log onto att.com and type in iphone 3gs in the search bar. and you can chose between 8gb 16 gb and 32gb.
by juggling you nuggets for a while.
if you want to record videos, then you can find tons of apps that will allow you to shoot videos.
