I was rather excited to find that there is now a $10 App called NetShare available which effectively allows you to turn your iPhone into a wireless modem. Once installed, you can access the net through your computer. I think this looks like a great little App, and at only $10 it is a real steal. Many people have complained about how hard they are finding the initial set up of the App; however I have located a tutorial article that can guid you through the process step by step. The link to this can be found after this jump. The only downside to the App is that people with FireFox 3 may not be able to install it however it is proven to run fine with FireFox 2 and also Safari.
I like these sorts of Apps as I think it is a reflection of the true capability that the iPhone has. It is not all just about style, the iPhone is showing it has real substance and I must admit I really enjoy looking through the Apps Store and having a look around at what is on offer. It is this 'kid in a candy store' element that I have not ever experienced with a mobile device before and I am constantly eager to find more hidden gems within this device!
