Uh... I didn't understand half of what you said. But ok thanks for that info. All I know is when I use it, it feels pretty fast but not as fast as my cable modem that I am using when connected wifi. Personally for me, BT is more practical because I don't worry about battery life on my phone. I don't use it very often and for long periods. Because, as we all know, if you're not paying for tethering, and you get caught... well you know the rest. Honestly, how often do you use this feature? Most of us have internet access at home. There's access in almost every coffee shop. Even some Denny's have them now.
