I love the new goodies in 2.0, but I think that the rumored memory leak is getting really annoying. At first, I just had some occasional app crashes or apps that reset the iphone. But now I seem to have angered it, requiring me to turn my iphone off (red slider) and on to get things working properly again every day or so. The latest symptoms are the "click" sounds (when I turn the iphone on or off) disappearing. I haven't experimented yet to see if other sounds, like alerts, are also being disabled. This started after I upgraded a few apps over the weekend. I'm not sure which may be the culprit, but I upgraded AIM, Facebook and Mobile News. I use those apps every day, and eventually the memory leak symptoms begin. Anyone experiencing similar issues? I'm glad that 2.0.1 and 2.1 have been spotted in testing, so hopefully these issues will be resolved soon. It is just sad because 1.4 (or whatever the last one was) was so rock solid for me.
