Yes, the OS seems very snappy indeed. One interesting thing I noticed is that when I loaded .743 with Master Control Program I didn't install the stock 18.104.22.168 BBM because I have the beta version from RIM and I figured it would be best to just do a clean install of 22.214.171.124 and I tried installing BBM several times but couldn't get the icon to show up no matter what so I had to wipe the phone again, reload the os with the stock BBM, then upgrade to the beta. This time when I installed .862 I made the same mistake again by not loading the stock BBM with the OS (I was sleep deprived and it was late). I tried installing the beta fresh just to see if I could avoid re-loading the whole OS and this time it worked just fine.
p.s. someone should ban this John Clark character, what is he thinking posting so much?
For real though, if he hadn't bumped the thread to the top like he did with all the posts I wouldn't have noticed .862 was released for another day or so, for that I thank you Mr. Clark
