The Apple iPhone in the U.K. has officially stopped being exclusive to O2 starting today. Orange is offering subsidized iPhones and pay-as-you go but will not compete with fees that O2 is currently offering. So it’s a level game there in Britain for both iPhone providers. Forecast from Mediacells is saying that a million iPhones will be operated through the Orange network providing revenues of £795,065,695.77. Yes, Medicell rocks on research if they can forecast the last cent earned from iPhones. The insight company lowers its projections for the Orange iPhone depending on cost for unit with £250 per unit projected to bring in £500,000,000.

Already there are 250,000 pre-subscriptions for the Orange iPhone. If these pre-subscriptions all sold during today’s launch, Orange will be second to AT&T’s first iPhone weekend.
