The iPhone is "not as fully featured" as other top-end devices, according to industry experts, but it does have "other features".

Software and telecommunications consultancy Ovum claims that high-end Nokia devices are more developed, highlighting that the iPhone handset does not offer JPS and is "only 2.5G".

However, the firm argued that these deficits are made up for with other features such as the greater ease of use the touch screen provides.

Jonathan Arber, a spokesperson for Ovum, commented on whether the iPhone is value for money.

He said: "I think it depends on what you're looking for entirely...It does have a lot of attractive features, but on the other hand it is very expensive, so it's up to the individual consumer.

"The price is a sticking point because if you're a consumer and you go into, say, the Carphone Warehouse and you're interested, it's £300."

Apple launched the iPhone in the UK on November 9th at 6.02 pm in Carphone Warehouse and Apple stores.

Users benefit from free access to 7,500 Wi-Fi hotspots but must buy the phone with an O2 contract.
