Is there a difference between these two methods of resetting the iPhone? - Hold top left button, then slide finger across screen to power off. - Hold top left button and home button for 10 seconds. The first method seems to initiate a "shut down" procedure with the rotating "busy" indicator for 5 seconds or so. The second method of course shuts it down instantly. I'm just wondering if the second method gets you a better reset (ie. clears the memory more completely). Because it would seem to be more of a brute-force approach that could perhaps introduce data corruption if a write operation is occurring, while the first method gives the phone a chance to close things down. In all cases where I've see the instruction to a 3rd party app recommend a reset before use (the bigger memory-hungry apps like X-Plane), they talk about the second method.
