The contract VM has with Y-Mobile is for network wide access, if T-Mobile adjust there network then access would be granted across its new footprint, this has lways been stated by Virgin as an "exciting proposition".

Unless there will be renegotiating of any contracts then Virgin customers should see the beenfits as soon as the networks merge, bear in mind this may take a few years.

One thing to watch out for is Femto-cells, Vodafone has launched theirs already and no doubt Virgin will launch something as well, this should eradicate dead spots in your house!
