If apple finally got influenced by the AMOLED wave... maybe we'll see a super AMOLED retina display or something?? I'm sure that the production of those panels will higher and the technology will be cheaper over time...
And oh, how about specs that is good enough to support iOS5? Maybe an A5(A4's successor??) chip? It seems that for every iteration of the iPhone, the iOS is fully supported by that year's iPhone... so, expect a much better iOS too...
How about 1GB RAM? Those are getting cheaper by year, and maybe by next year they'll be cheap enough for Apple to include in each iPhones?
I know that the current iPhone 4's battery life is awesome, but... maybe Apple could add more juice by next year?
Also, how about widgets?? Since HTC and Samsung are equipping their smartphones with those, only time will tell when Apple will put widgets on their iPhones.
It is possible, after all, the graphics of the iPhone will only get better right? And more RAM would be useful.. So, there wouldn't be any lag, and the dream of having Dashboard on iOS would come true! Maybe as a homescreen even!
Apple could also add more memory to the iPhone 5, 64GB would do some justice...
And I know how this hurts, but how about enabling flash? Maybe not by default, but at least put it as an option under the settings or something... But honestly, by how the mobile Safari is handing the flash videos, I don't think they'd need flash on the iOS.
I don't mind a trashcan of some sort where all deleted apps or movies can be stored in...
And maybe Apple could come up with more enhancements of iOS's GUI... I have no idea, but I bet people in Cupertino have tonnes of ideas, waiting to be experimented and implemented
Yeah... that's pretty much it...
