Less than a month after the iPhone 3G S was released, a host of patents have cropped up including Apple's ideas for object and face recognition, text message filtering to censor out swear words, a crazy voice changing feature and a smarter message interface.
The latter would see the iPhone returning text messages to you that weren't delivered to the recipient, and also alerting you to unread messages and emails from a contact before you make a call to them. Clever stuff.
Of course, patents are just hints at what Apple is considering, not what we can definitely expect – but it's always nice to get a little insight into what future incarnations of the beloved iPhone could include.
