Everything on the iPhone (from 3GS forward) is already encrypted afaik. That's how remote wipe works instantly (by just deleting the encryption keys)

This is incorrect. Device encryption on 3GS and later devices are only for 1) Apps that implement Apple's device encryption API (ie, stashPro now has this) 2) If you have a strong password set and 3) Unless you have a device released with iOS4.x, you will need to wipe, then restore it with the flag turned on
