I'm on the churn
I bought a Skype phone from 3 because i use Skype instant messaging extensively. .. Or at least I would on the mobile, if the Skype system worked on the phone. latency of up to 24 hours for phones in the same room ditto form a pc to a phone, now on my 3rd phone and the second the credit has gone, I'm offski. 3 may commission adverts of their operatives putting up masts for better reception in wild and wooly places , but they cant get a chuffing signal to my gaff in Eastbourne...
Perhaps the low churn is due to people trying to use Skype to cancel their contracts.
