Hi guys,took Dave .m's advice and phoned BT,who said the mac codes are valid for 30 days (as Kitz stated) and I could apply for the mac from the 10th of sept.Any outstanding charges will be calculated on the day I leave.
Just to add,our BT account is in my partners name but I want my new BB to be in my name ,I don't think this will be a problem (will it?) as its only the mac code I need.
The only reason it is in my partners name is because I can't hear very good via a landline phone(especially trying to converse with Indians)O2 support is UK based and free from mobiles (The clarity from a mobile phone is a lot better for me)
