External antenna to boost internet signal?

[SulphurDave]

Unfortunately I am right smack dab in the middle of 3g coverage between Houston and New Orleans. So I'm stuck in 1x. I had to go to Houston last week and noticed my phone switched from 1x to Ev automatically for the first time after wondering if it even worked. I want to use my phone as a modem for my laptop. I've tried it and it works great and all however... 120 kbps is lacking for wanting to use my laptop for web browsing, streaming videos, video messaging etc.

So my question is shouldn't there be some sort of external power booster antenna that I can hook up to my phone and laptop to receive an evdo signal a hundred miles away?
