Woooaaa, hold on. So if I understand this correctly, cpu is constantly at 600 mhz during phonecalls (or only when initiating a phonecall?). If that's the case, wouldn't longer phonecalls (1 hour+) be dangerous for the cpu, according to Nokia? Maybe that is why they advise against oc's and why the standard kernel maxes at 600. Now that I wrote that, it really doesn't make sense, since even on oc'd kernels the value decreases back to 600... Thanks again for the kernels, Lehto and Titan.
