That would be ace. I have been reading the situation last night and this morning& I am sure loads of people on here, including myself would be very interested in having a standard format letter that has been proven to have worked. I'm not sure vodafone realise there is a forum here, where I'd guess around 90% of n900 owners visit, and that adds up to a LOT of customers.
There will be a lot of android users that read the android forums too, maybe not as much as a percentage, but probably at least as many vodafone customers there that will want to end their contract.. It's like vodafone don't know there's an internet and news travels fast on it.
