Is it worth buying the iphone 3g 16gb?

Hell no it is to outdated now seriously rubbish.

The iPhone 3G is very outdated and it is no longer supported with updates from Apple because of it's older specs. At the least you should buy an iPhone 3GS which is still supported but only comes in 8GB new. The iPhone 4 and iPhone 4S are much more practical choices if you're simply looking for an iPhone and not wanting a brand new iPhone 5.

At this point, no. It is no longer updated so apps will eventually not be able to work for it.
