I took mine on our boat yesterday. I have the 3 G one but guess what? Even though AT&T says they have 97 percent of the wireless market it would only give me EDGE out there and it was too slow to even load a page. I have Sprint for my cell phone and I forgot my phone otherwise I would have been able to tether it to the phone. I knew there was a reason I don't have AT&T for cell service!!
