Right you are

No, enTourage didn't disable updates for the full-sized EE as far as I know.
The "Current Software Version" that nzimas posted suggests a version 1.6, but that might be the version of the Android OS (1.6). My "Kernel Version" under Settings -About eDGe shows "2.6.29buildmaster@zeke #1".
@nzimas: can you post what "Build number" says under Settings - About eDGe?
