Henry joins 20:20 as group business development director, the role initially offered to Motorola UK boss Jim Michel before he reneged last month.
Henry said: I have seen every distributor up close and 20:20 is way, way ahead of the competition. It could take ownership of the end-to-end supply chain of every retailer, network and manufacturer in the country. There are massive opportunities in the UK from supply chain consolidation.
Henrys first ports of call for broader-ranging distribution contracts will be Carphone and Orange, where he worked as sales director from 2002-05.
20:20 has also appointed Trevor Price, former chief executive of online retailer E-Directory, as UK managing director. Price replaces Peter Hubbard, who left in June after just six months in the job.
Former Carphone directors George Steur and Richard Parry have also joined as group commercial director and business development manager respectively.
Steur headed up Carphones European operation and, more recently, was responsible for its Best Buy joint venture in the US. Parry worked as trading director with Henry at Carphones SIM-free distribution arm Mobile Phone Express before it was canned last month. He replaces Richard Baxendale.
20:20 also confirmed last week the appointment of Chris Stephenson from Total Home Entertainment as UK finance director.
20:20 chief executive Mark Ryan said: We have never ever bought and sold as many units in the UK as we are doing now. We have never been further ahead of the competition in the UK. The gap is getting wider. I have a better quality and depth of staff than before. The team, from top to bottom, is the strongest weve ever had.
