Hats off to Jeff! Easy upgrade for all of us thanks to Jeff's excellent work.
The Sprint nojunk version has been running perfectly for a week now with no problems. This is truly a faster and MUCH cleaner ROM image. The only minor known glitch is the picture messaging/MMS (which I never use anyway – maybe someone has a workaround – text messaging is fine for me) and the need (as someone indicated) to kill the ActiveSync WCESCOMM process in XP before using Internet Sharing to tether (and adding your Sprintpcs userID and password to the Sprint connection) - certainly not show stoppers.
I'm running the standard goodies like MortPlayer, TCPMP as well as OnCourse Navigator (LiveSearch works well too using Com4 for the bluetooth GPS BT-33

, Microsoft Voice Command 1.6 (don't forget the Apache Fix for the buttons if you need it), Remote Display Control, Opera 8.6 , Netfront 3.3 (when string search is needed – PIE seems better now though so I’m mainly using that with the SPB PP plug-in), TRE, VJDeviceLock, SPB Pocket Plus 3.1.2, SPB Backup, Sprite Backup, SlingPlayer Mobile (Orb via IE, Media Player). I did a hard reset and restore from my Sprite Backup and that worked fine too to restore my fully loaded AKU 3.5 ROM personalized (I thought that was worth testing).
I also sync my contacts and appointments/meetings with Exchange and still have 30MB free storage and 27MB free for programs, even with VC1.6, SPB PP and ActiveSync running.
I can't believe how fast the PPC-6700 boots now and everything runs snappy (everything). Yeah, the BT drivers built in now still skip but I'm not sure if that is the drivers or player or devices - it's certainly not any worse.
Battery life seems very good. Great work! Definitely a keeper!
