So if you take the information provided by the web link this is potentially a major change for customers.  What the flyer doesn't say is, is it all happening at once, or will it be phased in over a period of time (VTV first, followed by landlines, followed by HFC upgrade) or all at once in one hit (ha ha I hear you laughing).  Many people will have security systems that rely on the landline that will need to be migrated or the systems will need to be upgraded/replaced.  I'm interested in the data speeds that will be offered on the upgraded HFC link as they may well incent me to remain with Voda after the T-Box has gone otherwise there is little or no incentive to stay given the number of companies offering fibre.
