Sierra card with Sprint service works in BT3beta live usb hard drive install with changes
I used this setup:
Phone number: #777
Username: email@example.com (replace 1234567890 with your data card's "phone number", no dashes)
Password: your sprint password
Speed (BPS): 921600 (use lower numbers such as 115200 if you have trouble with this)
Init string: ATZ
then I do this after each reboot, not sure if it is necessary each time.
modprobe usbserial vendor=0x1199 product=0x0120
the sierra wireless has details for other carriers
That's why I say hey man nice shot. What a good shot man.
