Since the enTourage is running 1.6 (I think), software outdated by 2.0, 2.1, 2.2 and soon 3.0 you will probably encounter many apps that are just too current, using APIs not supported by 1.6.

I recommend installing it using adb install filename.apk and see the output, alternatively you can use the logcat tool to view a lot while its happening or shortly after.

You shouldn't need root access to read logcat.
