Thanks to many months of rumors surrounding an iPhone 5, there was widespread disappointment when Apple unveiled only its iPhone 4S early last month. But despite this, the fifth-generation device is on track to become the most successful iPhone yet, selling 4 million units in its launch weekend alone.

If you didn’t pre-order the device for a launch day delivery, you’ve probably been struggling to get hold of one as Apple retail stores and supported carriers struggle to reach the overwhelming demand.

However, Apple seems to be keeping things in order, and continues to expand the reach of the iPhone 4S to new territories. Following its roll-out in an additional 22 countries — including parts of Europe, Mexico, and Singapore — on October 28, the Cupertino company is sending its new device to another 15 countries next Friday, November 11.

The 15 countries chosen to get the device next are: Albania, Armenia, Bulgaria, El Salvador, Greece, Guatemala, Hong Kong, Malta, Montenegro, New Zealand, Panama, Poland, Portugal, Romania and South Korea. Pre-orders for the device in most of these territories will begin this Friday, October 4. However, according to Apple’s press release, pre-orders will not be available in Albania, El Salvador, Guatemala, Malta, Montenegro and Panama.

Today, the iPhone 4S is available in 29 countries around the world, but it’s launch is far from nearing completion; Apple aims to have the device in at least 70 countries by the end of the year.

If you’re in one of those countries listed above, will you be pre-ordering your new iPhone 4S this Friday?
