I loaded it last night. I now get over 6 weeks of battery on only a 50% charge, with all radios on and all Social feeds set to update once a minute!! Also, my 9900 is now waterproof with this build and I noticed as well - that when I put it in the bath, it now floats!!! I can't believe it - this is the way the phone should have come on the 1st release!! Maybe it's because I'm on a BES though...not sure a BIS only 9900 would behave this way...
