A couple of quick notes about today's release of an iPhone (and iPod touch) 2.0.1 bug-fix update:

• Updating a jailbroken device. I applied the update to my jailbroken iPod touch. It updated the device without any glitches. The presence of the jailbreak software/firmware did not cause the update to fail. Nor did installing the update result in a bricked touch. I didn't even have to Restore the touch. The update just worked. The only problem (not surprisingly) is that all trace of the jailbreak software is now gone. I am back to a stock iPod touch.

Will the same Pwnage Tool jailbreak software that worked for 2.0 still work for 2.0.1? I doubt it, as it appeared to be firmware specific. But I cannot yet say for certain, as I haven't yet tried.

Will an update to the jailbreak software be released for 2.0.1? I am confident it will be. In the meantime, I will be monitoring the various iPhone jailbreak-related blogs to see what's happening.

• Updates and backups. The update of my (not jailbroken) iPhone 3G also went well...except that the increasingly long time it takes to backup my iPhone is getting to be really irritating. When doing a sync, I can always choose to cancel the backup (the rest of the sync then proceeds as usual). With an update, however, there is no option to do this. So I just had to wait over 45 minutes for the backup to complete. Sheesh! I hope this is one of the "bugs" that is fixed in the 2.0.1 update.
