Thanks to improvements in the iPhone OS 3.0 software update released Wednesday, connecting to a Wi-Fi hotspot with your iPhone or iPod touch should become almost as easy as roaming on the cellular network. Two new features radically improve the process of logging in (when you've already got an account with the Wi-Fi hotspot provider) and filling out information when it's required for free access. However, there are some catches, and-wouldn't you know it?-an incompatibility or two.
There are a few apps in the iTunes App Store that let iPhone and iPod touch users share data and even play games against each other over the Internet. PosiMotion even makes a few. But the developer has gone the extra mile to create hardware to help users within range of each other share and play to their hearts content.
