How to set a data limit on my iPhone 4s?

When is the new iMac to be expected?

I've heard various rumours for a while now. Originally, rumours spread that there would be a new iMac announced in September 2012, alongside the iPhone 5 - but that didn't happen. Now, rumours are spreading that the new iMac is to be expected in October 2012 - it's mid-October now, and I haven't heard anything official.

I've been looking to buy an iMac ever since the current model was released, but never had the money (as I'd like to use it for my graphic design work). Now I have the money, I'd like to get the new iMac when it arrives - but I don't know when it is! :/

I don't want to buy the current iMac model, and then a month or two the newer model comes out. That would suck. And that's happened to me before with my original iPad. I bought my iPad, then a month later the iPad 2 was released! And at a lower price! I was gutted.

But anyway, does anyone have any clue as to when the new iMac is to be released?

What are the Whatsapp basics?

So a girl I know lives in another country and wanted us to use whatsapp to talk instead of email. How I do that? I have her in contacts (with her country's code) but all I can do is send some generic message inviting her to get whatsapp. She looked for me and said she couldn't find me. She uses a Nokia and I have an iPhone 4s by the way with the ios6 update if that means anything. Can someone give me some possible solutions for this and maybe even just a basic walk through with whatsapp?

Porting Verizon wireless prepaid number to Page plus?

So i have an oldschool flip-phone samsung gusto thats prepaid(bought from walmart). I want to upgrade, yet still have the power to pay through prepaid. Page Plus is a company thats part of verizon too, so i was wondering if its possible to port only the number to a iPhone 4(carrier=verizon of course).

From what i've read, prepaid number can't be ported or something along that line. Also i'm a college student, so thats why i'm on a tight budget, as everyone else probably is.

Greatly appreciate any help.

What is this icon on my iPhone?

Basically I have an iPhone 4S and when I double click the home button the app history comes up. When I slide right the music player comes up, then if I slide right again my volume thing comes up. But next to the volume thing I have this little icon which looks like a triangle pointing upwards into a rectangle. When I click on it it says iPhone with a tick next to it and it says cancel at the bottom. Anyone know what it is?
