I really like the upgrade so far. The browser seems faster and I like the media manager as its easier to load pics onto my device. The pic caller id is pretty sweet. If you can get accustomed to the new theme then you shouldn't have any problems. I lost the browser after restoring my info but after registering it came back over night. Also you can attach pics to email messages which I seemed to have a problem with before. Also I was unable to make 3 way calls even though I'm subscribed with that feature, but after the upgrade it works now which is a huge plus for me. Also I use a nokia bluetooth earpiece and so far people I talk to say it sounds better. Volume seems more consistent and louder on calls thru the speakerphone I haven't yet tested the Bluetooth Dialing for EVDO tethering but after I configure and test I will let you know my results. The voice note feature on BB messenger works as promised. The operation of the phone seems a tad slower especially switching between apps (alt cancel). Also it was kind of cumbersome on the desktop manager when adding caller id to contacts, and the roxio media manager is a little slow but has nice options for quick editing (red eye removal, cropping, etc.). It took forever to open as some of the pics I was grabbing was through the network. It crashed and I ended task and then when reopening it went to the last folder I was on which was over the network and it took a bit. I had to choose a local folder (my pics) then close and reopen for the setting to retain itself. Anyway, I'm off to bluetooth tether I'll let you know my results.
