OK, about a week or so later:
Data connections are rock solid. Since the last post I made, I've had no drops. I've also made sure to let the boot scripts complete before messing around with the phone. Handoff from 3G to 4G and vice versa (made on a daily basis, I live in 4G but work in 3G) have been perfectly fine.
GPS - I have only had a single issue of GPS issues, earlier yesterday when it all of a sudden popped up saying that the location I was at does not exist (LOL! I'm in a timewarp!!!!). 5 minutes later the message disappeared - I assume the phone retracted its statement once it realized just how foolish it was being....
Overall, I'm liking .905 better than .904, but I also realize that I went to .904 about a week before my city received 4G, so I cannot compare it to .902 and the handoffs and GPS there.
HTH
Per a PM, let me clarify:
I'm making my comments from CM9 SelfKang in safestrap.
