Briefly: Mac OS X 10.5.3 update, new Apple ads, iPhone supply issues (UPDATE)

UPDATE: Apple has posted a third build of Leopard this week with one bug listed on the seednote.

Here's a brief catch-up with this weeks' news:

Mac OS X 10.5.3 seeded to developers

Apple has seeded a couple of Mac OS X 10.5.3 update builds to developers since last week, sources informed MacScoop.

This update is set to bring hundreds of fixes and could be released before or during this years' World Wide Developers Conference (WWDC).

Apple posts new iPhone and Get A Mac ads

Apple has started airing and made available on its site a three new iPhone and two new Get-A-Mac ads.

iPhone:
- Music Store
- Brilliant
- Bet

Get-A-Mac:
- Breakthrough
- Yoga

The company had recently posted a few other iPhone ads:

iPhone out of stock

It appears that Apple is experiencing iPhone supply shortages in the USA. The shortages are rumoured to be linked either to the success of exported iPhones -now that it is possible to unlock the device in one click- or to the imminent introduction of a 3G model.

The company has responded to the press and denied the rumours of an imminent new model and claims that it's rather a too high demand issue.
