Played with the GPS some more. After installing the APK in the OP, Maps automatically does an update (version number remains the same). If your Navigation App crashes, try this:
Clear the cache as follows:
Settings->Apps->Maps->Clear cache (I think this cleared Data on the same menu as well. If not, clear it).
To make the system a bit snappier, try the following. First enable Developer Settings as follows:
Settings->About Phone->Build number (tap on it 7 times)
Now go to Settings->Developer Options
Set Background Process Limit to "At most 3 Processes"
Unfortunately, this setting is not sticky and it resets with every reboot. Worth playing with if you have a lot of apps open at the same time. I played with the different options and opened as many Apps as I could. 3 seemed to work the best for my needs. Since the setting is not sticky and I can't be bothered to do it every time the phone reboots/powers up, I stopped playing with it.
Wifi works - just an issue with my router. For some reason, this phone never worked with my router, regardless of which ROM I used. No problem connecting with laptop, tablet, etc.
Only major bug to report now is that Bluetooth doesn't work - same problem as Zbreezy1. The slider switch can be flipped but it never comes on and then goes back to off automatically. A minor bug: The Cell Radio slider doesn't actually turn off the cell radio. This would have been great if we wanted to repurpose the phone as a Media Player later.
BTW, Zbreezy1, my contacts didn't sync up at first (similar to your calendar problem). Here's what I ended up doing:
Go to Settings->Google (under Accounts)
Click on your gmail address. Various apps will be listed. In my case, there was an error by Contacts. If you touch the icon, you will get the option to resync. For some reason, that was the only App that was out of sync. I probably rebooted the phone as it was syncing.
Overall, I'm pretty impressed with this build. I really liked AOKP 4.2.2 for it's stability (at least for the first 2 months) but this one seems to be snappier and has a nicer interface. I hope the Bluetooth issue can be easily fixed. Thanks for your hard work Phenom!
A noob question: When I was playing with the different settings, I somehow brought up a list of the active Apps. I've done it accidentally a few times, but I can't figure out how I did it. Any ideas? Also, has anyone tried any wifi hotspot apps with this build? I tried Wifi Tether but couldn't get it to work (versions 3.3 or 3.4)
Sorry about the annoying bold and underlining - I figured that those two sections are the most relevant to anyone scanning the posts quickly
