The venue also featured a demo room where the media could try out the new handsets which were pre-loaded with exclusive music content.

O2 has been 3´s roaming partner since 3 launched in 2003. 3 invited UK networks to tender for the roaming contract 18 months ago and the network said Orange tendered the most competitive bid.
3 UK CEO Bob Fuller said: "It was important we had a competitive tender and I am delighted with the outcome of the process. This is a good agreement for both 3 and Orange and will ensure that we continue to offer a great service to our customers."
An O2 spokesman said: "We weren´t prepared to win at any cost. Our bid was based on a sound commercial proposition and we weren´t prepared to go above our valuation. You have to set a price that you think is realistic and stick to it."
He added: "We will continue to benefit for some time until all of the roaming traffic can be migrated away from our network next year."
3 has continued to roll out its network and now claims to have 88 per cent population coverage. At the same time subscriber numbers have grown to 3.5 million. Orange claims 99 per cent population coverage.

He joins from 4U Ltd where he was also national sales manager and has more than 12 years´ experience with networks service providers retail and distribution.
Fone Logistics director of network sales Giulio Laise said: "We have been looking for a while to make an appointment to support the management team. Allan will be a valuable asset in growing our business and will contribute to our achieving the annual operating plan."

"We think this is the best commercial deal out there" said Adam Shaw from UK Phone Solutions. "People think it is so good that they have asked us if there is any small print they should be aware of."
The Web´n´Walk deal encourages mobile users on to the Internet for a flat rate of £17 a month with a new Web´n´Walk datacard.
"We believe that broadband mobile will change the way we work live and play more even than mobile voice has done" said T-Mobile sales director Simon Ainslie.
"We have led the way with open internet access for mobile and with speeds that already well exceed dial-up. Later this year we will launch true broadband mobile speeds."
Web´n´Walk Professional potentially offers users Internet access at speeds six times faster than 3G. The card is also quad-band allowing users to roam in more countries including the US.
"In the past people were worried about how long they were using the Internet on their phone" added Shaw. "This plan means that is no longer a consideration. I think in time it will become the norm in the same way broadband did."
Ainslie added: "Until today cost has been a barrier to customer take-up. Now Web´n´Walk Professional makes Internet access on the move a reality. "

The acquisition makes Go Mobile the industry´s fifth largest independent dealership with 35 stores. The stores will be re-branded as Go Mobile. Go Mobile takes on around 30 staff from A1 Comms.
Go Mobile managing director Iain Humphrey said: "The purchase of A1 Comms makes absolute sense. The footprint works well for us. We will keep growing the chain in a good professional manner. There is good business out there for independent dealers that write the type of business that the networks want with regard for ARPU and tenure."
A1 Comms managing director Paul Sisson said that only 30 per cent of the company´s revenues came from its retail footprint. The remainder came from corporate and web sales both of which have much lower overheads than retail.
"The bottom line is that running 10 shops on the high street is very difficult" said Sisson. "You are better off having either many more outlets or much fewer. Iain Humphrey is in a much better position to make a success of it because his chain of stores is larger. The sale is in the interests of both me and my staff."
Sisson will continue to run B2B sales under the A1 Comms brand and will spin off the web sales business www.buymobilephones.net as a separate limited company on June 1.
A1 Comms retains its Orange OBS and O2 Advanced dealership status.
"B2B is great because the networks love you because they love B2B customers" he added. "We gets lots of support and that business is going from strength to strength. We sell up to 100 phones a day from the web site. We are keen to concentrate our efforts and grow these businesses."
Nine of the 10 A1 Comms stores are in Derbyshire and one is in Nottinghamshire.

A full compliance audit by Samsung adds its Samsung Level 2 Service Centre accreditation to Fone Logistics´ existing Nokia and Sony Ericsson accreditation.
"Working with Samsung will prove of significant benefit to our customers particularly given the impact the manufacturer has made in the market over the past 12 months" said Fone Logistics operations director Lynne Gillespie.
"I expect this announcement to be followed by other strategic relationships and service agreements."
Trained operatives within the Fone Logistics Service Centre will handle Samsung repairs and the company has undertaken a programme of continuous improvement and training to ensure the latest handsets are supported.
