Overall I like the new version of the software, although I'm not a fan of the additional bloatware that was installed (Which I'm not allowed to remove without modifying the phone).
I've noticed two bugs that are very annoying.
#1 - The proximity sensor is now not working properly. Every time I hold the phone between my head and shoulder without using my hands, the screen turns on and my face starts pressing buttons. This was *never* like this before, and is highly annoying. A basic ability of any cell phone is now not present.
#2 - The "Contacts" application will not close. It remains resident in memory using between 10 megs and 40 megs of ram. If you force close it, the entire desktop disapears for a few seconds before returning. This was not like this for the last update.
