This is a relatively new blog site and has a lot of great information about drivers and applications for EVDO/UTMS/3G adapters in Windows 7. Having a hard time getting proper support from Sprint/Verizon/AT&T/HP/Dell/etc? Go to this site first!
And on an even better note, there are actions underway to do away with most of the 3rd party connection software tools that seem to be the root cause of most of the Windows 7 connection issues.
The following manufacturers are on board: Acer, Asus, Birdstep Technology, Dell, Ericsson, HP, Fujitsu Siemens Computers, Huawei Communications Technologies, Option, Qualcomm, Sierra Wireless, Smith Micro, T-Mobile International, and ZTE.
