The iPhone has a "wipe after 10 tries" setting, but they can back up your phone and then try 10 tries on millions of virtual images of your phone in parallel.
I'd recommend coming up with a
passphrase that you can memorize without writing it down.
Hypothetically you can carry a dumbphone, but it's contents won't be encrypted at all and any calls made are in the clear.
I wish they would implement a two level passcode system. The simple code that unlocks the basic operation of the phone and a more complex one for anything sensitive--but which can also provide authentication to apps and websites. You decide what things go in the secure bin (say, banking stuff) and have only one code to deal with. It would also support a duress password that exposes some but not all of the stuff--put some red herrings in there.
