iNetwork Test allows you to measure the download speed of the Internet connection your device is connected to as well as the latency of the network. The application stores your last 10 results, including speed, latency and location at which the test was performed. Results can be voluntarily transmitted to the iNetworkTest.com website, building a global database of performance information for the iPhone/iPod Touch on WiFi, Edge, and 3G networks. Additionally, you can choose to sign up for a free account that will store all your results online; plotting them on a custom map.
** 3G and EDGE tests are now working on European Carriers! Thanks to Apple and the Carriers for their help in getting this sorted out. **
