Network Port Scanning With iPhone, Network Discovery with iPod Touch, Network Troubleshooting with iDevices
I purchased an amazing application from the iTunes store tonight for my iPod Touch called iNet created by Banana Glue. In a nutshell the application makes it very easy to discover all of the devices on the network that the iPhone or iPod Touch is currently connected to. It is by far the best forming application in this class that I have seen.
There are many things that make this application stand out above the rest. The iNet home screen provides links to the each task including Scan Network, Ping, Bonjour Browser, Wak on LAN, Device Info, and Settings. Below I will provide a brief explanation of each of these tasks.
