Just letting you know initial experience. I followed instructions from Cingular (install connection manager first, then insert card, etc.). Card initialization worked fine, and sending sms did also, but no go on internet browsing, and after the software install, my laptop went haywire. CPU pegged on random app; couldn't open control panel, honestly - - very weird. Took out card, rebooted (had to kill it, wouldn't do it gracefully), removed conneciton manager, rebooted, and installed the Sierra software to see if it would upgrade firmware. I guess it didn't need to update (didn't prompt for it), but after this, everything is good.
Stationary in hotel right now on Edge network with solid 5 bars and it says it connected at 1.8Mbps (thought that wasn't possible on just Edge, but whatever) but download / upload speeds are around 85kbps (which is what's to be expected on Edge..it's the broadband connect that gives between 400-700).
Anyway, will keep folks posted on in-car performance and what it's like when it gets 'broadband connect' connections.
I am thinking about doing the same thing. So it would be nice to know really how fast these things go. I would like to drop my cable and just go wireless.
