– Lock screen music controls: The music controls on the iPhone’s lock screen have been enhanced as noted by TUAW, bringing them in line with those in the Music app.
The shortcut controls, accessed by pressing the home button twice while on the lock screen, have adopted both the look and layout of the Music app. One notable change is that the previous and next buttons are now much further apart from the play/pause button, making them much less likely to be pressed accidentally.
The volume knob also copies the Music app’s visual trick of using the phone’s accelerometer to vary the angle of virtual reflections on it.
– Maps “Report a Problem” button: Apple has tweaked the “Report a Problem” button in its Maps app, accessible in the preferences section by tapping at the lower right corner of the map page. The option had previously been a small text link, but Apple has now made it a much more prominent and accessible button which is actually now the largest button on the page.
– Rapid diagonal swiping issue improved: Several readers have noted that an issue with rapid diagonal swiping on the iPhone 5 and fifth-generation iPod touch resulting in loss of touch recognition appears to have been fixed or at least improved in iOS 6.1. Not all readers have experienced improvements, however, with some indicating that performance remains the same under iOS 6.1.
