Why would Apple make FaceTime only compatible with iOS devices?

It doesn't make sense what if someone has an Android! Then FaceTime is useless to the person with the iPhone who wants to video chat with the person with the Android. Someone please tell me why Apple did this, I know it's a stupid question but its bugging me

How many extra gigs on iPhone?

I'm getting an iPhone 5 for Christmas and am not sure how much space I will need. On my 4th gen iPod touch I'm using 25 gigs. I was considering getting a 32 gig iPhone, but that only leaves 7gigs to grow. Is that enough? Does storing contacts and photos take up a lot of space? Should I opt for the 64 gig instead?

What are your opinions?

Can I keep my jailbroken apps after updating then rejailbreaking?

I have an Iphone 4 jailbroken with firmware 5.0.1, so I want to update to IOS 6 then rejailbreak with redsnow (not sure if one is out yet but one will eventually be made) Is there a way I can keep my apps taken from Installous? I'm aware Cydia and some other apps will not transfer because I have updated and rejailbroken before, but didn't know at the time if there was a way to keep apps such as games. I also have the itunes sync option in Installous set on.

Does and iPhone 3GS have built-in internet?

I want to buy an unlocked iPhone 3GS, but I don't want I plan. I was planning to get the app, TextPlus, and just use it as a phone for free. However, I know that TextPlus requires an internet connection for it's uses. Does the iPhone have internet built-in, like Airplane Mode, or do I need to make it a hotspot? I hope you get my question. Just so you know, I want to use it as a phone even when I'm not in Starbucks or McDonald's or something…

Added (1). So I can use it without a Wi-Fi connection? By the way, sorry if I sound stupid…

Why isn't my iPhone charging? - 1

So, new software popped up for me to download for my iPhone3. After it finished loading. It seems to have turned off and I can't get it back on.

I'm having trouble connecting to Wi-Fi? - 1

I have dell latitude d810 laptop with windows XP installed. (I know it is quite old but everything is updated, service packs and all) Network adapter is working properly along with network discovery. I can see and click connect the my home's wireless internet, but when I do it does NOT connect. It does work if I have the cable wire plugged in directly, but I need it to be wireless. My iPhone and direct TV are connecting wireless so I know that it is not the router.
