Loaded Gingerblur last night, so limited amount of time with it but WOW. Not only is the battery lasting longer, but I noticed it charged faster than before. Over all speed of the phone is probably faster, I say probably because it was so fast before I don't know if what I see is actual improvement or just the wow factor. What I can tell you is when running before I could only ever get about 380mg of ram available, even after a fresh reboot and after having frozen (via titanium backup) all unneeded programs. I have been able to get 550 available and that is still with a couple of random widgets running. Just to show I am unbiased i will say that I'm not real happy with the look of the new Messaging app, but have downloaded another one which solved that, also when plugged into HDMI it does a true mirror but that wont go into landscape to show movies and such, I just installed a zip that is suppose to fix that but I am not home yet to see how well that worked. Also did the battery % zip and love that. It shows the battery percentage right in the battery icon at the top of the screen, I had a Battery widget going just so it would show me this, so one less app running and cluttering things up. Calander widget doesnt work, that is a known problem and so far they dont have a solution that I found.
Overall Gingerblur is awesome! It does have a few negatives, but the Positives pile so high you cant even see the negatives anymore.
