I installed ultrasn0w to fix the 1 signal bar issue (I'm on AT&T), it murdered my battery. I can usually go 3 days without having to charge. I barely make it a full day. In 2 hours of standby it went from half battery to 20% warning.

Removed it and now the phone lasts forever so 4.3.1 did add some extra battery life.
 
Are people with 4.3.3 1.59.00bb combo having those mms/vmm issues? There is not that much info about this around. It seems that with 4.3.2 the problems still occured.
