iOS 4 launched to great fanfare on Monday, and various outlets have provided their respective opinions on the new platform.  Daniel at TodaysiPhone (our sister site for all things iPhone) picked up a copy of iOS 4, and did a fantastic job of covering the new improvements and features of the new operating system.  I certainly learned some interesting things that I didn't know (you can't lock the screen in landscape mode, for example).
