Hak5.org has very good podcasts. In one of them, they are surfing the internet on a laptop tethered to a blackberry. I was under the impression that BBs didn’t have a Dial-Up Network service in them. But I was proved wrong. I made it work in Windows XP and now in Vista 64. This means that I can work in the bus, really work in the bus. I can access license servers… I might be able to read e-mails from the HelpDesk. Man… freedom.
Well, accessing license servers is taking some serious time.
Now for the tough question, how secure this is? I am VPNing into the office right now, so this should be safe. Point to point. As for surfing, I am not going to download p*rn on a 55kbps connection.
Happy as a clam. And I thought that Vista 64 sucked… well, still does, but now a little less.
Uh, oh, and how did I do it?
