Apple iPhone fever begins to grow

Apple's iPhone goes on sale in the UK and Germany on Friday with thousands expected to snap up the device.
Eager customers have begun queuing outside the Apple Store in Regent Street, London, despite the poor weather conditions.

But there are concerns that consumers are only able to use the phone with one mobile network.

In the UK the phone will only work on O2's network, while in Germany T-Mobile will support the device.

The phones can be unlocked for use on other networks but this voids the warranty and could break the device if software updates from Apple are loaded.

As many as 250,000 users in the US have unlocked the device using free and paid-for software to make the phone work on different networks, and to load third-party software not supported by Apple.
