Will the Iphone 4S be around for 2 or more years?

I have the android right now and my plan is over in december of 2014 and when my plan ends I'm switching to an iphone. Will the iphone 4s be around by then or will it get old?

You can still get a 3 and they've been out for years. I suspect you can get a 4 or a 4s in a couple years.

It'll definitely still be around in 2 years time, or you may be able to get the next-generation iPhone in 2 years time, as it'll obviously be cheaper by then.

Why would you bother asking now about what you might buy 15 months from now? And if it's old, so what? You won't have the newest phone.

Anyway, if Apple sticks with its products cycles, they will have released both the successor to the 4s and the successor to THAT.
