It has been announced that the UK launch of Nokia’s Lumia 900 has been delayed until mid-May at the earliest. It seems that the overwhelming success of the US launch has caused shipping problems for Nokia’s flagship handset.

A spokesperson for Nokia said: “The overwhelming demand for the Lumia 900 in the US with AT&T has, unfortunately, had a small knock-on effect on product availability in the UK.”

The spokesperson added: “The Lumia 900 is now expected to be available from Phones 4u around 14th May.”

The unprecedented success for Nokia in the US, and especially the white version of the Windows Phone powered handset, has apparently taken Nokia by surprise. Whether this translates into success in Britain though cannot be taken for granted.

Interestingly, this supposed delay was not confirmed as such by Nokia, as the Finnish outfit had not given any official date for the UK launch.

Windows Phone 7 currently powers the Lumia 900, but experts think that by the time it arrives in Britain next month WP8 maybe available, so upgrading will not be far off.

In other news, Apple has announced that its Worldwide Developer Conference will take place in San Francisco on 11th June.

While traditionally this particular conference is the time when Apple announces its latest developments, seemingly the company is coy about whether iOS 6 will be launched.

If you fancy going to this event but have not bought a ticket, then unfortunately you are out of luck. It is completely sold out.
