TidBITS has an interesting write-up on the various security features of iPhone 3.0 in general, and the 256-bit AES hardware encryption of iPhone 3GS in particular, and how combined together:

consumers can now experience enterprise-class security.

They cover passcode lock, data erase, remote wipe, lack of insecure external data cards, frequent and easy to install software updates/security patches, and (encrypted) backups that can restore your data if your device is accidentally wiped. Definitely worth a read if you tend towards the security conscious.

UPDATE: Engadget heard from Drew Herdener, Amazon.com's Director of Communications:

These books were added to our catalog using our self-service platform by a third-party who did not have the rights to the books. When we were notified of this by the rights holder, we removed the illegal copies from our systems and from customers' devices, and refunded customers. We are changing our systems so that in the future we will not remove books from customers' devices in these circumstances.

Good on them for coming clean and changing the policy going forward. Though it would have been nice to have the candor and insight up-front.

ORIGINAL: According to Engadget, Amazon has remotely wiped copies of George Orwell's classics, 1984 and Animal Farm from Kindles, refunding the purchase price of affected users.

We're not yet certain, but users of the iPhone Kindle app are probably similarly effected.

It remains unlikely that Amazon broke into any houses, repossessed any copies of same, and left change on the bureau.

By contrast, when Apple removed NetShare from the App Store, already purchased copies remained -- and remain to this day -- on the devices of whomever purchased them.

Takes a lot of wrong to make App Store policy seem right these days, so way to go, Amazon. You've either redefined ownership in the DRM age, or broken faith with any customers thinking of owning any more Kindle content...

As part of the WWDC keynote today, Apple announced new features for their MobileMe service as it pertains to the iPhone:

• Find my iPhone shows map location
• Find alerts sends text or sound to advise of lost iPhone or help find it

• Remote wipe lets you clear data from a lost iPhone, or restore it via login or iTunes

• Mobile iDisk App gives access to viewable files right on your iPhone

• File sharing lets you send links to files via email with access control
• Access public folders lets you share files on your friends' iDisks

Like iPhone 3.0, the MobileMe updates will be available June 17.
