Just got a 4S after 2 Androids , 1 blackberry, and 1 windows phone.  A friend insisted iPhone is great for Ham operators.  I have to agree that ham apps seem to be better on iPhone, though for developers Android rules!  There are definitely things I would love to see changed on IOS, but can get used to it.  Eg.  On android you had a back button.  When you backed all the way out you generally got an exit menu.  Without any menu and just closing the app I sometimes wonder if my data was saved. Beyond that there are a few things that seem smart, but I think I would still prefer a few more dedicated buttons.
