Hi guys, I'm looking at buying an iPhone to use with my existing O2 contract as I get unlimited web access already and a 40% discount on the tariff cost. O2 have said they dont do retention discounts for the iPhone, not even staff discounts. When I asked about using my current sim in a store purchased iPhone they said it would work but WiFi would not be enabled. Is there any way to enable WiFi on a standard contract sim? Cheers, Andy.
