The 3 options from the WM phones are 1) built-in DUN USB 2) built-in DUN BT 3) WMwifirouter.
I've been digging through the xda forums and it seems like there are no standard ways to use any of these 3 options.
For USB method, android does not have the required drivers.
For BT method, android does not have a built-in BT tether profile.
For wifirouter, android does not allow ad-hoc wifi connections.
There are some work around threads, like for ad-hoc wifi tether the kyros tablet is doing this with limited success:
for BT tether, seems like the archos tablets has a BT profile built-in:
Do anyone have a work-around or solution for the G-tablet?
Sorry if this thread is a repeat.
btw, its a bit difficult searching for this because most threads are about tether FROM an android device. In this case, we need to tether TO an android device.
