Android Phones - help with usb_modeswitch

[aaron d]

I'm sure you have searched around a bit so I'm not sure how much help I can
be, but I did find this:
http://www.windmobile.ca/community/ideas/detail/30173/
seems this works flawlessly for windows users (surprise surprise) but you
aren't the only one dealing with this under nix. I also assume wind is your
carrier since you mentioned the "unlimited" data plan.

Hope you get it figured out.
