The Solution
Greetings from Chile !!!
I had the same trouble, I hidde the customize icon and others, well I didn´t restore my phone... Here´s the deal....
With WinSCP go to the applications folder
Open the customize folder (Customize.app)
Right click in the customize file, select Custom Commands and the.. Execute
Take a look to your iphone and customize will be opened, put the eyeball in your hidden icons and restart your iphone. Turn it on and the customize icon will be in your home screen.
No need to restore the iphone....
I love the iPhone...
