I had Bazinga 1.6 since it came out. I upgraded from ZAPX RC2. I also have BigDX blue theme along with widget locker. The phone is also overclock to 1.2 ghz low voltage. Over all, Rom has been pretty stable except it would freeze few times a day under heavy usage and it would shut the phone down few times a week. I am aware that Droid X has issus with phone turning off on its own. As for the phone freezing up, I thought it was due to combination of the rom, theme, widgetlocker and low voltage over ckock. Too much stuff running on the phone. To make the long story short, I had Autokiller installed on my phone while ago and had it preset at aggressive. Since about 2 weeks ago, I changed the preset to Ultimate and since than, NO MORE SHUTTING DOWN AND THE PHONE RARELY FREEZES. Its fast, smooth and very stable. My average quad score is between mid 1500's to mid 1600's.
The only problem I have is with Gmail. When I send a mail, its stuck in out box. I constantly have to clear data on app manager. I know this is a known issue. Seems like no one knows permenant fix.
By the way, what's the differernce between Bazinga 1.6 and Bazinga 2.0? What about RC2?
