When researching devices, i came upon a review that said something like "you can sync the V4/4s via bluetooth with your phone, or via wi-fi with both the phone and a computer". I thought this was a great advancement. I will be able to sync data or get updates or upload music to the watch, either through bluetooth and the phone, wi-fi and the phone, usb with the computer or wi-fi and the computer. Now that i own the watch, i don't see the use of wi-fi. It doesn't work with the pc when thy are both connected to the same network, neither with the phone. Phone requires bluetooth, pc requires usb. When i go to the phone settings and select to connect to wi-fi, it says "transfer in progress" and "transfer complete". I don't understand what exactly gets transferred each time. For example i don't understand how the weather gets updated, it seems it can only get updated if you have both bluetooth and wi-fi turned on, on the phone, and have the bluetooth turned on in the device. Any help?
