Tether BH II is super easy, much easier than most of us expected. If you have Cradlepoint router, you just need to setup APN and that's it! Make sure your phone USB mode is "samsung studio" and USB debugging is optional (it doesn't matter it's on or off). If you want to tether through USB with XP/Vista/7, you need to download the following application http://img.samsungapps.com/support/Kies_188.8.131.5271_32.exe use 7zip to unpack, and go to \your location of the fiile\Kies\CabFile\USB Driver, unpack the .cab again and go to the unpacked folder. Run the .exe file and wait till it finished (there's a driver not included, which is used for debugging/development) Now, setup dial-up networking modem: samsung mobile modem number: *99# Have fun, just don't do anything stupid and get caught!
