If you ask me, people should stop whinging. On which other range of phones can you take a handset that's two years old (the original iPhone) and enable most of the new features of the latest models purely through a free software update?

Of course new models will have some new features. That's how the company makes money. What do you expect them to do - invest lots of money in developing new software features, and release them all to existing phones for nothing?

That's just not how it works. The company can't improve its products and make a profit if it doesn't sell new handsets.
