Hack into your Sony PSP (for 2.0 - 2.8 firmware)

This new Sony PSP image-based exploit (via a buffer overflow in the PSP's libTiff image library) enables you more recent PSP firmware havers to run your own homebrew software on the device. Clever hack, but as with the other previous hacks and firmware versions, this exploit probably won't work in later firmware versions. Couldn't Sony make things easier for everyone by just providing a not too easy to get to switch of sort that would let the PSP owner run their PSP in homebrew mode or not? Couldn't they have a disclaimer that basically states

if you flip this switch, you can do what you want with the PSP but it will void your warranty if you break it. To protect you from yourself, don't flip this switch unless you know what you're doing and even then, don't call us for help...
