The colored puzzles pieces stopped appearing for me as well once I installed Handcent SMS.
I'm gonna disable Handcent and see if the pieces return to the lock screen.
I got it pretty early in the morning. I can so far notice 2 things.. The signal bars are much more visible and crisp. Scrolling left/right home screens no longer lag. I guess we'll see what else.
after the update i have not been able to keep my text notifications on. im using hancent and i have a alert from zedge ringtones. the alert will work for maybe 10 min then it goes silent. ive tried a "stock" one and the same thing is happening... very disappointed here and im past my 2 week grace period
Not a biggie, but I was just curious what others were seeing.
OK, the puzzle mystery has been solved. It was the Verizon messaging app that caused it. Once I deleted that app, I got distinctly different puzzle pieces depending on whether I was getting an incoming call or message. Weird.
