Apple is unlocking German iPhones following Vodafone's success in raising an injunction against network partner T-Mobile.

In Germany, customers can buy an unlocked iPhone for €999. The phones aren't unlocked at point of purchase - the unique IMEI code is sent to Apple and registered on the company's database, once that's done the device can be unlocked using iTunes

Vodafone successfully argued that Apple's exclusive arrangement with T-Mobile was illegal under German consumer law.

Meanwhile in the UK reports have begun to emerge which claim UK users are having problems with their iPhone's signal strength. The problem may be related to the device's battery, as signal strength tends to go up following the iPhone being placed on charge.

However, these widely-reported criticisms of signal strength emanate from just 100 replies on an Apple discussion forum page.
