The GPS Receiver, by design, will provide GPS coordinates to any app that requests it, and the vast majority of apps on the iTunes App Store will work with the GPS Receiver. (A partial list of apps we’ve tested with the GPS Receiver is here.) If you have a question about a specific app, here is a simple checklist you can follow to determine whether or not an app will work with the XGPS150:
Step 1: Make sure that the app you are considering is available for download onto your specific device (iPod touch/iPad/iPhone). For example, not all apps on the iTunes App Store work with the iPod touch or the iPad. Read the app description before downloading it onto your device.
Step 2: Read the entire app description carefully to determine whether the app requires a network connection. If it does, and you are looking to use it on an iPod touch or an iPad without the 3G service, most of the time it means that you will only be able to fully enjoy the app when in a WiFi hotspot.
It doesn’t necessarily mean you shouldn’t use the app, but it could be that some features, which rely on the network connection will not be available when you are not in a WiFi hotspot. Many location-based apps do not?require a network connection, and you can fully enjoy them with the help of the XGPS150 on the devices that do not have a network connection.
