John McKerrell has been posting recently on his experience developing an iPhone application for the ‘Free The Postcode‘ project – the project aims to build a free collection of UK postcodes (why?).

Interestingly, I found John’s application surfing the application store on my iTouch; it’s a smart move by Apple to put such consideration into providing a market place and distribution channel for application developers. John has shared the download stat’s for his FreeThePostcode app…a staggering 3000 downloads in just a couple of months – for an application that targets a niche audience – all very impressive.

Matthew Somerville has also built a similar iPhone application for FixMyStreet.
