In my opinion it makes sense to always go for the 'main' versions of the iPhone

[shenfrey]

Because - from what has been seen so far - the S versions always seem to be incremental, with a faster processor and an improved camera with maybe a new feature, as last years was Siri.

But the reason why I think its easier always going for the main versions is because by the time the next number is released - iPhone 6 in this case- you will be ready up upgrade from your previous 24 month contract. The next numbers tend to always be the bigger upgrades as well.

Anyone else agree with me on this, or share a different opinion? Let me know, I enjoy hearing other point of views : )
