The link to version 2 appears broken; Dropbox says no file found.
Also, before you posted this version, I successfully installed the .19 radio, but whenever I try to install the drivers, I am unable to connect to the data network (T-Mobile USA). I'm running CM9 Beta 10. I've tried it several times, including wiping cache and Dalvik cache before flashing the drivers, and then the EFS wipe. I also tried it on MexDroid Fried Ice Cream 3. When the G2 starts up it connects:
Signal Strength (roughly): -898 dBm
Mobile network type: UMTS:3
Service state: Disconnected.
Model: HTC VIsion (T-Mobile G2)
The latest update works for me, installed the updated radio and the Wifi Calling zip that includes the radio drivers. Thanks, you rock!
