by this time next Friday, i'll be a Vodafone, T-Mobile or Orange customer and i wont be on O2 anymore
which should i go for out of T-Mobile, Orange & Vodafone?
and if i want to join Orange, since my 6600 has been used on an Orange contract by a mate of mine (i bought it off him), would that effect me if i gave them the IMEI for it as its already registered in his name? (but he has a D500 on O2 contract now, the IMEI is written in the book for the 6600 but if it was contract, it would have been cancelled with Orange, in which case... The IMEI of the 6600 shouldn't be in anyone's name)
