This deal I shall point out is only available instore.
If you buy an IPhone 4 on a £35 a month contract and work for (or have family who work for) NHS, Councils and many more you may be entitailed to 25% off your line rental. I should also point out if you work for a large organisation who uses Orange as their main provider for mobile contracts you might be entitailed to this deal, as I was informed in the shop.
The best deal I see on the £35 a month contract has to be a 24mth contract with 400mins, unlimited texts, 750mb with free sat nav with orange maps and 50 photo messages.
Its a great offer if you can get it as overall for the time you have the contract for the 24mths it costs you overall £700.
