I’m hoping the version 4 software will sort this issue out on the iPhones GUI, but for now this is how I’m grouping my apps. Trying to find a certain app on pages upon pages of colourful icons has been bugging me for a while. I seem to find myself scrolling endlessly left and right searching for an app before forgetting what I was looking for in the first place. I came up with a little solution I thought I would share with you, maybe some of you do it this way already, but I find it far easier to group my apps in to categories on each page, so:
Page 1 is my most used apps. (I’m sure most of you do this already).

Page 2 is for Photography related apps.

Page 3 is for navigation and travel.

Page 6 is miscellaneous apps that I only use in a blue moon.

Page 7 is for the junk that you can’t delete which comes with the iPhone.

It might look a bit of a waste having pages half empty, but trust me, browsing for a certain app is much faster this way.
I hope this helps some of you out. let me know how you get on.
