Here to report everything is working fine for me!*
Stock Rom: 2.17.671, using the
update from here
The Updater ran smoothly, no errors (Mogul disconnects and only says 11%, PC continutes going up)
First Boot: Sprint Customizer takes about 2 minutes
Boot Screen, shows "Test Only"
My Device screen: Oddly, my Current Username is different than what it used to be - in the past it was nickname@sprint something. I'm not sure if this makes a difference.
Starting Google Maps for the first time. Note that it does take a while to find the satellites the first time around. GO OUTSIDE TO TRY THIS!
Google Maps working!!! It's about 10ft off from where I'm actually standing.
I've also confirmed that telephone calls are still working fine.
*Note that my brother also has a Mogul and first had several errors during the update process (error 270 communication error). He's also reporting trouble getting a signal and EVDO. so YMMV!
