I'm really not sure if this a bug or setting adjustment. When the phone goes in the sleep mode, it will not wake at all and I have to pull the battery. This happens intermittently and there is not one app that it does it the most. I have Zip's 4.03 on my phone, but it has been doing it with all the Zip ROMs. I've searched dev forum and I can't seem to find anything, so it's probably something with my phone. I tried to make adjustments the performance settings with both the built in set cpu and the setcpu from the market and it still happens.
On this last update, I formatted data and dalvik cache and flashed the ROM in CWM and the aroma installer came up with no problems.
Again... love the ROM and don't kill the posting Newb. Just trying to help out.
