Is it practical to buy Iphone 5 or just wait for the release of the latest Iphone?

I have been using Samsung Galaxy 3 and have decided to try apple products as they say it's much durable than what I have now. I just don't know if I should try Iphone 5 now or just simply wait for the release of the next Apple phone product maybe before the year ends or early next year.

If you wait for the release, more things will be avalible for you to do with your iphone. It would be a wise decision to save up on the newest one

The next iPhone is expected to be announced on Tuesday. So you should wait for that & get that if it satisfies you.
