CYPHERC: Have you tried turning auto-rotate on the phone settings to OFF? Once I did this my problems with answering calls virtually disappeared. I still occasionally have a problem accepting calls if I am typing or scrolling at the time but otherwise my phone works fine. I have installed Phone Speakers Switch which gives the prox. sensor a good workout and usually dial out via K9 Call. As for your Media Player and other problems all I can suggest is a careful re-flash of the FW (both images). It took a couple of goes on mine to get a clean install. My music player occasionally stutters when first playing but very soon settles down. when playing videos I occasionally get a stutter or a jump but this is so rare it is not a problem. You may have issues relating to apps you have downloaded - I have experienced problems with some early releases. It's a pain but the only thing to do is reflash and individually download apps so you can monitor performance and anomalies/bugs. I found Conboy very useful for keeping a log on this. The only multitasking and/or slow-running problems I have seem to relate to Bluetooth use - I'm still working on that, but it is only a minor irritation. I am not a developer or have any programming insight to offer. I am a 'technologist' in the sense that I cannot tell you how electricity works, but I know how to change a lightbulb! Good luck sorting your N900. I hope you get it to the stable, useable state that I enjoy on mine.
