Update: The Apple Store is now back online. While there are no obvious changes to the store itself, T-Mobile has begun to accept pre-orders for the iPhone 5 on their site.
The Apple Store has just gone down, which is usually a precursor to Apple opening up pre-orders for new products. However, no new products have been announced so far this year, so this outage is most likely for maintenance purposes. So relax, we probably won’t see the iTV, iWatch or new iPads, iPhones or Macs when it comes back online.
