I've had a couple of months now to play with the various SYNC functions in my GCMax and wonder what the Wifi connection is actually for. I've connected it to my home wifi and tethered it to my mobile phone but been at a loss to understand what I can do with it. The menus seem to be kind of cut down and although it suggests that apps can be downloaded, you only have a selection for software updates - which I guess are SYNC updates. Are they? I also wonder why I need to tether my phone to SYNC in order connect wifi enabled devices when I can do this directly to my mobile. Anyone got any ideas?
