While we’re all busy getting excited about the possibility of tethering for iPhone 3.0, Android users are still mourning that fact that Google pulled a tethering application from the app store because it violated T-Mobile’s terms of service.
Considering there was a news story on here not long ago about T-Mobile releasing a new 3G-Modem, I'm not surprised they yanked those apps. No reason to undermine your own business.
It might be nice, but I'm still not sure where I would have adequate 3G access and not have WiFi. Airports may charge for Wifi, but like your going to get a meaningful 3G signal sharing a tower with 10,000 other cell phones.
Does anyone use Cell-phone tethering other than to avoid paying for Wi-Fi or home internet access?
