Apple has published an 'open letter' regarding the coverage issues with its new iPhone 4. Here's the entire letter:

Dear iPhone 4 Users,

The iPhone 4 has been the most successful product launch in Apple’s history. It has been judged by reviewers around the world to be the best smartphone ever, and users have told us that they love it. So we were surprised when we read reports of reception problems, and we immediately began investigating them. Here is what we have learned.

In this week's edition of The Fonecast we discuss the reported problems surrounding the launch of the Apple iPhone 4 – and we take a look at the rest of the week's industry news, from mobile TV and roaming charges to Symbian and Android. In addition, there's a visit to Good Technology to learn more about its mobile email service.

eBay has acquired the RedLaser barcode-scanning application, which lets iPhone users identify products and find online information – including prices - simply by scanning the product barcode.

RedLaser was previously a chargeable app. It's now been turned into a free application, which is likely to see a dramatic increase in the number of downloads. The paid version had been downloaded over two million times.

A report today from comScore reveals that iPhone owners consume more mobile media than people with other handsets. (Admittedly some might argue it's not much of a revelation because the iPhone has been designed for this purpose).

The Apple iPhone has just 4% market share in the UK, France, Germany, Spain and Italy, although iPhone users represent 12% of all mobile media users. comScore's report says 94% of iPhone owners use mobile media, 87% use applications and 85% browse the mobile internet. The average for all smartphones is 65% mobile media, 53% web browsing and 53% app usage.
