More Color options although with their problems producing the White phones, not sure this will happen.
Hey let us customize the icons, and system sounds, SMS, MMS, Chimes, Tones etc for Calendar and everything - they can even sell in the iTunes store and ppl will buy em'
Ability to disable any apps that you do not use, kind of like the Nike+ and YouTube, but let the user decide.
Longer Life Battery & some type of Battery manager.
Dump the Glass on the Back, it seems to only be causing issues and it is not very strong, also it makes the unit seem heavy.
Ability to turn off Multi-Tasking, I personally do not use it, but I know there are others that do, so put some ability to turn it on or off pls.
For those looking for more space, give em' the option for 64GB or 128GB but Please do not get rid of the 32GB model, I do not want anymore space then that.
There is my $.02 Cents to the whole topic
Why would you NOT want more space? Don't get me wrong, i purchase whatever is the smallest at the time (minus the 3G, white was only the larger model) because i only use about 5GB of space total.. but why would you prefer smaller? If they offer 1TB and 2TB in a few years, i'll never use it, but i'll be more than happy to take it all.
