So about the battery issue and Opera, I found this thread on XDA forums and I am wondering if it has to do with the fact that NRG enabled Internet Push with this release. Read up on it. I'm going to install the cab file that disables Internet Push which apparently goes out and loads your favorites every hour and keeps opera open all the time. Read up...maybe this is at least part of our battery problem. I'll post tomorrow and let you all know if it made a difference on battery usage.
