Depending on what iOS you have it varies, if both iPhone 4 and 3GS had iOS5 the only difference would be not having the switch camera button in the Camera App and FaceTime.
You Cannot Download Facetime to the iPhone 3GS because of its lack of a front camera, apple will not give you that option. However, if you plan to upgrade to the 4s if your 2-Year Contract is almost done, then it comes shipped with iOS 5 and Facetime free. I hope this helps.
Yes, they should be able to. The iPhone is backward compatible. Yes, they can. I used to have an iPhone 3GS and all the games work on my iPhone 4.
You can download the FaceTime App in your Iphone, Ipad, Mac or Kurio tablet
If you are using a Mac, you can download the FaceTime app of the Mac App Store (You may need to update you Mac Software If you do not have a Mac App Store). On a iPhone 4 or iPhone 4S to FaceTime select the contact you want to call in the Phone App or in the Contacts App. Instead of taping on their phone number, scroll down and you will see a button that says FaceTime. You must be connected to a Wi-Fi to use FaceTime.

The iPhone 3Gs was released in 2009. This model was a touchscreen smartphone with a camera, internet access, voice control, typical phone function, and app capabilities. Since the release of the iPhone 3Gs there have been a few updates. The most recent iPhone is the iPhone 5.
No software is required to use Facetime on the iPhone 4. It is required that you be on a WiFi connection. Facetime can only be done from one iPhone 4 to another iPhone 4. If you are using Facetime on a jailbroken iPhone then it is possible to Facetime chat with out using a WiFi connection. Simply go into Cydia and search for a package called My3G. This app allows you to trick your iPhone into thinking is it on Wifi connection allowing for Facetime chat over a 3G connection. An alternative to using Facetime would be Skype. Skype can be downloaded in the Apple App Store. Skype is video chat that can be done from iPhone 4 to iPhone 4 or iPhone 4 to a computer or computer to computer.
