One of the changes to 1.3.8 was static licensing to support functionality without internet connection and those who use their EVO overseas. This introduced a crash on phones with a specific device_id, but it got fixed in 1.3.8a.
Another addition is the "Report a problem" option when you hit the menu button. This will automatically pull the logcat and paste it in an email message and will be sent directly to my dev email.
Currently working on a Landscape UI and more audio route options for those with a HDMI->DVI adapter or a bluetooth headset.
Thanks! Will test today and report back
