Well, kind of. T-Mobile is giving out cards good for one free day of WiFi through their hotspot system. I picked up a few, and after giving my DNA checksum to T-Mobile was on.
The bad news: for some reason sending mail through the SIMS authenicated SMTP server doesn’t work. Not sure if this a T-Mobile issue or a SIMS issue. Next time I’ll probably just stick to my 115Kbps Bluetooth dialup. It’s slow but at least I don’t have to fill out forms.
