Help needed from I-Phone using friends. DD Taryn wants to get an IPhone but doesn't have a lot of cash to spare monthly. The cheaper deals seem to be with the IPhone 3GS ... is there any benefit to the IPhone 4 above the IPhone 3GS. Also is the 3 network any good as this seems to have good deals for unlimited internet which is what she would need. I can get a good deal with an NHS discount with Orange ( I think ) ... would cost £29 per month for 1GB internet plus Wifi, unlimited calls and texts .... is that a good deal ????? Only problem is I would have to get one and then get one for Taryn on same deal. Do I really need one is the question ?????? Any advice re IPhones and networks gratefully received as I don't have a clue. Thanks.
