I've joked before that BT & Vodafone should merge.
OK, it's (probably) not going to happen, but the next-best thing appears to be multiple cross-sell / virtual services.
1) BT Fusion uses Voda's network as a platform for its MVNO in the UK
2) Voda ZuHause in Germany uses BT's fixed-line & number translation wholesale services.
3) ... and now Voda UK is going to become a customer for BT Wholesale's broadband ADSL
Certainly confounds the expectations that Voda has to acquire broadband service providers....
What next for the Newbury/Newgate "rivals", I wonder?
