The main reason I jail broke mine was so I can have it looking how I want, why should Apple dictate that I should only be able to have six icons in my dock?, why should I waste all that screen space when I could fit twice as many apps on my screen?, I don't like grey so why shouldn't I be able to change the colour of the text for the apps name. It's my device not Apples so I'll have it looking how I want.
So now I've removed the lock screen so it's instant on, I've put nine icons in the dock and the dock also scrolls so I have another nine icons on my second dock 'page'. On my main springboard page I have no apps visible at all, vie hidden them all with iblanks so I can view all my wallpaper fully. For my top 18 apps I use the dock then for stuff I don't use everyday I have those underneath the dock, so instead of swiping from the right to move onto page two I swipe up the screen to bring the apps up from the bottom. I have my iconoclasm set to 6x6 or something like that, something that looks good in both landscape and portrait. I do have a page 2 of apps which is dedicated to just games, my games screen scrolls also so there's no limit (until my 16gb is full lol) as to how many games I can put on that screen. So now need at all for me to have more than two screens.
I'm really pleased with my layout now, I wouldn't buy a new iPad that couldn't be jail broke, Ive not got into altering themes, apps graphics, fonts etc so with the right cydia programs it takes like 5 minutes to set it up, though it did take me three weeks to decide just how I wanted things laid out, though once I had decided I've never changed it. No need for folders either, with all oft used appsnin the dock and games on page 2 I don't need ugly looking folders when all they do is introduce an extra button press into the equation.
