Question should be re-phrased slightly: did you get £2 movement on your account, and if not - are you existing T-Mobile customer?

I already have two pay monthly numbers with T-M and I didn't see any credit/debits on my account in relation to my N900 order. However, a friend of mine who also placed order with MPD and got new T-M contract (not being their customer, that is), indeed had these £2 debit/credit on this account.
