Is it possible to tether to a Blackberry connected to WiFi? I was recently in a hotel where I had a horrid cell signal and wound up buying a day of wifi for my Crackberry. I then returned to my room and needed to do something on a laptop. I tried Tetherberry to avoid double paying the fee, but it didn't work. I managed to connect at that hotel with both the same password on my Crackberry and notebook, but presume that this will rarely be the case.
Same thing in the sky. Now that planes have wifi, I'd love to buy a signal wifi subscription for both my Crackberry and notebook (rather than 2). Any suggestions?
