I would have loved Froyo if Verizon didn't add 10 lbs of bloatware that make my phone now run even slower than it did with 2.1.
Seriously considering rooting my Droid Incredible. HTC Sense certainly isn't worth it to me, all their apps are buggy as hell and crash sporadically.
Part of your issue may very well be caused by HTC and not necessarily Verizon. I don't know what Verizon specifically added to the various Froyo releases on the different phones, but regardless of what was added it was HTC that actually packaged it all together (something possibly added at Verizon's demand, of course).
But when did you upgrade to 2.2 ?
Most users' experience shows that the first day after the upgrade to Froyo brings about a very slow phone, as the phone has dedicated important resources to the background sync services, to download previously-installed apps and user account settings.
Even with added apps, not many of them actually run in the background (except for HTC services). Froyo is the first release that actually included JIT, which significantly improves performance across the board. I can't imagine why a phone running 2.2 at stock settings could possibly be slower than 2.1 at stock settings, beyond the first day of use at least. If it is indeed slower even after the first day, you might want to check if any of your currently-installed apps are slowing the system down, i.e. not as compatible with 2.2 as they may have stated.
If you are running any task killer services, uninstall them immediately. They are absolutely unnecessary in Android,
especially when on Android 2.2. Froyo has an even better task management system.
You may want to search the web for other users with the Incredible and 2.2, to see if anyone has determined if any specific applications may be causing decreased performance.
Thanks again Destrekor!
Does Verizon issue a change log for these different builds so I can see what they changed / fixed / added /etc?
You're welcome!
Changelog
Couldn't find a changelog for the first Froyo release.
And I couldn't find a more in-depth list of specifics, but that does seem to do a fairly decent job of covering what they changed.
If you are looking for the more specific list of changes 2.2 brought, and not the specific builds from Motorola/Verizon,
this covers basically everything.
