My wife and I got the iPhone 6 the other day and she prefers the larger icons (5 rows) and I like the smaller icons (6 rows). Not counting the bottom icon row which remains on each screen, do the iPhone 6 and 6 Plus both have up to 6 rows of icons? Or can the 6 Plus add a 7th? Frankly, since the 5s had 4 columns and 5 rows, I don't see why a 6 Plus can't at least accommodate 5 columns and at least 7 rows. Like on the iPad...why so much dead space between the icons? The 5s doesn't have as much dead space.
