Hey, iPhone 3G owners: Please do not download the 2,1 firmware files listed below. They are for the 3G S and will not work on your phone. Read the whole post for details. The correct firmware for the 3G will start with "iPhone1,2" instead.

If you were up all night waiting for the new iPhone OS to arrive, you're in good company -- we were too, until we began getting Twitter reports from users in Hong Kong and Sweden that the local carriers sent out SMS alerts to their customers suggesting when they could download 3.0. Those times both align with a 10 am PT/1 pm ET go time, and that's when we're calling it for now; Engadget concurs. That's why you're still seeing 2.2.1 as the most current version in iTunes; the new version hasn't been released yet.

curl -s -L http://phobos.apple.com/version |\
 grep -i restore |\
 grep '_3.' | open -f

The results will look something like URLs ending with this:

iPhone2,1_3.0_7A341_Restore.ipsw
iPhone2,1_3.0_7A341_Restore.ipsw

The model number indicates which unit has downloadable firmware. As of right now, only the iPhone 3G S firmware has been updated. That's the 2,1 iPhone model. Yes, the 1,2 iPhone 3G model was considered a revision of the first generation 1,1 iPhone as it only had moderate hardware changes. The two iPods are 1,1 and 2,1 for the first and second generation.

To download, copy the URL and paste it into Safari's download window or use any other favorite method to retrieve the firmware. Then hold the Option key and click Update in iTunes. Navigate to the firmware (the ipsw file), select it, and 3.0's good to go. Of course, you can also download directly through iTunes as soon as the update is available.

The question about the refresh isn't whether it will happen or not but rather when. We were guessing June/WWDC for a 3G iPhone announcement and September for a delivery -- after all, new cell equipment has to go through rigorous approval. Stock shortages indicate that at least a memory-based refresh might arrive sooner than later. Right now, Apple customers are experiencing 5-7 day shipment delays on their purchases.

I'd be sad if Apple discontinued the mini line even if I've had some issues with its design, particularly its lack of dual monitor support. I know that's a strange quibble to have with an otherwise well priced and moderately powerful unit, but it's the single issue that has kept it off the desktop of many of my friends and colleagues.

Thanks, fraserdrew.
