Apple keeps updating the iPhone, probably in hopes to stifle the hacks that people have developed to put there 3rd party applications on it. Apple has not been successful yet however. It is still easy to hack the iPhone and put the apps that you want on it. Another application that does that is this Mac OS X application with a GUI. This is a great application to get 3rd party apps on your iPhone with ease.
All you have to do is download the program to you Mac then turn off iTune and iPhoto and hook up your iPhone with the program running. It is as simple as that to get started.
I have tried looking for GPS for the iPhone, but have been unsuccessful. The best way so far seems to be to go to Mologogo and signup for free GPS tracking of a device. Then you have to get a cheap device that can be tracked and use that. Then you go on to Mologogo and sync the device with Mologogo and receive a link to your location. Then you type that url into google maps on your iPhone and you can see where you are currently located.
The problem with this solution is that it is not easy to get directions from where you are and it does not really keep track of where you are going unless you update it. this is a great idea, but it has not gotten me that excited since it is not quite to the point I want it to be and it still costs more than what I am already paying for. $600 for a phone should include GPS. Hopefully Apple has a GPS expansion application and hardware in the works.
