iPhone 2.0.2 Update, What Did it Fix?

I still have the 1st generation (EDGE) iPhone and for the most part it’s been working fine. Apple released firmware update 2.0.2 today via iTunes and as usual I promptly installed the update.
So far I can’t really tell if anything on the surface has been updated or fixed. I can tell you that prior to this update, going into Contacts seemed a bit slow, slow enough to make me think the app was hung. Scrolling within Contacts at times was also slow and jerky. Now, with the 2.0.2 update, Contacts seems to launch faster and the scrolling seems to have improved.
The App Store still has discrepancies between available updates within the iTunes interface and the App Store app on the phone itself. Right now iTunes shows I have four apps that have updates but the iPhone says I have one. Which one do I believe?
Another annoyance has been a delay in typing that has been present since the original 2.0 update. The 2.0.2 update does not appear to fix the problem and it’s too early to tell if the update has at least helped. One really annoying typing delay (for me) is when entering my Passcode after the iPhone has been locked. This is a policy requirement for the company I work for to use Exchange support. The first few characters always delay in both typing response and tick sounds as I type. I’ve also noted some early typing delays when using both Mail and Twitter apps.
One thing I’ve done prior to installing firmware updates is to reboot the iPhone with the two finger reboot. This seems to clean up any running processes prior to applying the update. I’ve also disabled crash reporting to Apple (via LifeHacker) during iPhone sync which seems to have increased overall sync and firmware update speed. I know what some don’t agree with disabling this “feature” but until Apple makes the process faster, I’ll keep mine disabled.
Only time will tell if the update has improved the usability of the iPhone or corrected “bugs” as Apple says. Please keep in mind that I still have the EDGE iPhone and 3G iPhones may experience different results.
