Hey guys ive attached a picture, look at my Dock its not supposed to have that bar going across it is it, ive reset the phone and obviously turned it off and on and things, will it require a restore to get it right.
Are you talking about that clear shelf? I'm pretty sure that's been there since.... i want to say iOS 4.
EDIT: oh wait i think i see what you mean. The line there. If thats the case that's just a problem that the picture you have as your background is not the size it needs to be. Find a taller wallpaper
This. That black bar is the blank background because your wallpaper is up too high. Center your wallpaper, or find one that fits, and it should go away.
I'm guessing your phone is an iPhone 5, and your wallpaper is at iPhone 4/4S resolution (960 x 640). It's too short... Find one that is the proper resolution for iPhone 5 (1136 x 640).
