I've been having trouble getting Temp Monitor to show up in my notification bar while running BB v0.4. Not a big deal but I do like to see my CPU temp as I'm using my phone.
Anyway, I seem to have stumbled on a "work around" for this. Just apply Pete's "Fix Permission" from ROM Manager. Please note: you'll have to do this every time you make a ROM change such as a different kernel or theme.
I'm currently running BB v0.4, Blue Energy Theme, P3 kernel at 1000 Mhz.
I doubt I've discovered anything along the lines of extra terrestrial intelligence but just thought I'd pass along this little tid-bit of information.
