Now that Steve has publicly stated that Apple will do their best to stop iPhone unlocking/hacking, or make it more difficult at least, I turn your attention to an advice from the Dev Team's site:

---
A quick reversible way to disable automatic updates : remove the executable permission on software_update

chmod a-x /usr/libexec/software_update

Since bbupdater is included in the updates, you must block all automatic updates to prevent baseband updates
---

One question though: is this an adequate measure against "forced" updates, or do we have other means to fortify our unlocked iPhones against unpleasant surpises?

Surely not updating your iPhone is good enough? I've just turned off automatic updates in iTunes. Do we need to do the chmod a-x command?

Steve said they wants to be one step ahead, so Apple is mouse /offtop

This needs clarification since there may be a few confused Mac n00bs trying to disable Software Update on their Macs.

The /usr/libexec/software_update binary is on the iPhone and is made non-executable by chmod as detailed above. You need a SSH server, shell and chmod command binary (the BSD Subsystem and SSH kit will do) on the iPhone to do this, or with the BSD Subsystem and the Terminal on the iPhone you can issue the command on the phone itself.

Note that there is no binary called 'software_update' in /usr/libexec on Mac OS X Tiger. However there is /usr/sbin/update - so just to make it clear - the utility you are disabling in this process is on your iPhone. You'll need jailbreak and BSD utils to do it.

Just to be certain, this wouldn't prevent a restore would it?

just another thought about "The cat and mouse game", Steve said they will do the same as what they do on music. and they finally lanuched DRM-free music on iTunes store...... if they are really doing the same, is that mean they are going to open up and have an offical unlock version of iPhone for purchase?

Good question. Anybody?

An easier method to do this is to install Squid (from Nullriver's Installer), browse to the file specified in the iphone and simply uncheck the X's in the execute boxes.

And this is completely reversable (all you gotta do is re-check the boxes if you want to allow updates). Completely noob proof... I hope!

Nothing is completely noob proof..... Never overestimate the understanding of a noob!
