I couldn't wait for the split keyboard option, but realized that the quirks that came with iOS5 far outweighed that one benefit.
Battery life is terrible, it becomes unresponsive or freezes when I type (especially searches), apps freeze and quit . Even the part I wanted, the split keyboard, causes the cursor to randomly jump to the bottom of an email, to my signature line, and continue typing.
I really want it gone. I know I can jailbreak it. But, can Apple do it for me and keep it "above board"? I don't want to void my warranty.
