Sorry for your frustration.  That said, you were working with early (
pre-raring ) developer preview images, in addition to porting to an
older phone.

It's up to you.  If your dad needs a phone, seems like that might be the
greater good in this instance.  See my note below about a possible
change we may make due your email.

It's not that the device is "low-end", it's that it's *old*.  There's a
difference.

OK.

At this point, we're still going to investigate making the "radio" user
change as discussed above.  Perhaps this will make things easier for
someone else working on this port in the future.

Thanks again for your help!
