I've made purchases using WiFi Store and thoroughly enjoy the functionality of the Home Button double-tap. (FYI...if your iPhone goes to sleep while listening to iPod you can double-click the Home Button and without unlocking the iPhone you are able to adjust volume/pause and play/fast forward and rewind) A BIG however... -Mobile Safari crashes in every instance where one inputs text or uses a drop-down menu and other times just plain crashes. (Please try TUAW.com for example EDGE mostly) -iPod feature crashes frequently (3 times per hour of listening) -Using the two features simultaneously is no longer an option. Many times just clicking Mobile Safari while listening to the iPOD causes an instantaneous crash. -SMS is now delayed 3-5 seconds when opened regardless of how many conversations are stored. Please try to duplicate the TUAW.com crash as well as the apple.com/feedback/iphone.html crash; using the text fields causes a crash on EDGE only.
