Webpass, if you live in one of their on network buildings, if you just mean no longer having a regular telco pstn/dsl/cable modem.<p>For pure wireless, enh.
I've been trying to find the answer to this too. I currently have AT&T DSL in the west portal/parkside district of SF and I can't get more then 4mbs connection. All their higher u-serve service isn't up to date in my area. Slow internet sucks =(
