I recently broke my N900 so ended up with a replacement, looked brand new so i was happy, turned it on and the welcome video is all glitchy :S, got all my apps back etc. Loaded the power kernel profile ideal, playing away on it then it crashes and reboots :S, so I stick it on ideal again couple of hours later it does the same, it feels slower aswell, my media player plays the first 5 seconds of any video (inclu.youtube stream) and goes back to the main menu lol. I miss my old one I had it running at 900mhz most of the time on the ideal base profile with no hassle. Thought I'd share that with you. Lol.
