I have my droid clocked at 800mhz and using the BB rom. Loving it so far!
I use SetCPU to both overclock my phone and also monitor the battery temp. you open SetCPU, then hit system info. Battery temp is the first thing.
Then i use temp monitor. it puts the cpu temp in the top left taskbar. works pretty well. it seems to be almost the same as the battery temp all the time. does this app really measure cpu temp?
