The past week or so when I press the home button, there is a very noticeable lag. When I slide my finger to unlock it may take 15-20 seconds for it to actually unlock. Applications wont respond, which forces a battery pull. In some cases I've had to perform a battery pull multiple times in a 20 minute period. Same symptoms... batt pull again. I've had this happen mutiple times on different days and is getting quite annoying. Anyone else running into this... and find a resolution? Any help or ideas appreciated.
