Just wanted to share the good news about the latest evo upgrade. I was scared to death to upgrade because I was one of those whose phone turned into a brick during the first update. What made matters worse was hearing the horror stories from some people about owning bricks after the latest upgrade. Still, there seemed to be a preponderance of positive reports, also. I decided to take the dive. After I initiated the upgrade, I didn't touch the phone until it was finished (took quite a while so be prepared to wait. Go wifi if you can.
Boy am I glad I upgraded. My battery lasts twice as long (rough estimate). On low usage days I got three days out of a charge (extended battery). The other really cool thing is the quick start up time. It used to take around 45 seconds (guess) before I could use my phone. Now, the phone is up in a few seconds! For me, that is awesome. I didn't lose any apps that I am aware of and the phone functions smoothly. Putting the phone in vibrate is less easy though because that feature is missing from where it used to be. That is the only thing missing that I miss. I have a mute app that works very well, however and you can still go into set-up to get vibrate only. If I notice anything else I will share it. Good luck! I love this phone!
