Customers who rushed out to buy the iPhone 5 when it was released last month may face having to pay an extra £120 for the privilege of using EE’s exclusive 4G network when it launches on 30 October. T-Mobile and Orange owner EE, which will be the first network to launch faster-than-3G mobile Internet speeds in the UK, will reportedly apply a £5 per month surcharge to account for the costs associated with readying its existing infrastructure for 4G. The company has yet to comment on specific costs, but acknowledged that it will prove to be more expensive for phone users.

Japanese giant Sony has decided to halt the sales of its Xperia Tablet S, just over a month after unveiling it at IFA in Berlin. This is due to a major manufacturing issue, as the tablet contains a gap in its rear display panel, making it vulnerable to water damage. In a press release, Sony apologised and vowed to inspect and repair existing owners' Xperia devices for free. The defect does not raise issues of safety, and Sony has not revealed when sales will resume.

One apology is the extent of Apple’s humility, it seems, with the iPhone 5 manufacturer following its recent bout of iOS 6 Maps grovelling with a more characteristic fit of contempt. Responding to widespread reports of a mysterious camera defect affecting its latest handset, the frequently belligerent US company has announced that the Instagram-like ‘purple flare’ effect ruining photographs on some version of the iPhone 5 is, in fact, “normal.” Apparently, the problem can be remedied by the simple action of "moving the camera slightly” away from the offending source of light. In other words, blame yourself or blame the sun – just don’t go a-whining to the Cupertino-based company or their Geniuses.
