Upgrading:
Wifi Fixer will be routinely updated.
When it is, you will be given a Notification by the Android Market.
The process is identical to any other app, you simply tap Update and the app will download and install.
However, because Wifi Fixer depends on a background service, you must open the app or reboot your phone after updating to start the service.
By Google design, there is no way to have a service automatically start on install.
Important: If resources in an app are changed, odd behavior can result on update.
If this happens, either uninstall and reinstall the app, or reboot the device.
