Is it worth getting an iPhone 3GS?

They are sitting around $230 NZD, whereas the iphone 4, and 4s are sitting around $400-$550 NZD on trademe. (like ebay). I need a smartphone, but want a half decent one thats cheap (ish) too. Is it worth getting a 3GS now that the 4, 4s AND 5 are all out? I don't care about being 'cool' and having the latest one, just need to know if its any good!

Based on what I've read, it's a good phone unless it's important to you for a phone to have a front camera for video calls. On the other hand, the newer models have a front camera and the iPhone 5 has a larger screen size (4 inches) compared to the previous models which are 3.5 inches. If you don't care too much about screen size, then go for 3GS

Well the 3GS is no longer made, so that's a negative. It does get updated still though, which is good but since it is the oldest of the currently updated iPhones it will be the 1st to stop being updated & that will definitely be before iOS 7 later this year. Not a matter of having the latest one, just one that wouldn't become obsolete too soon afterwards.

If anything go for the iPhone 4 at least.
