Well the tariffs (plans) for the iPhone for for my network (o2 UK) came out today and they've taken away our unlimited data and replaced it with 500mb p/m, for lower monthly tariffs, to 1gb p/m, for the most expensive monthly tariffs.
I'm most likely to get a mid range tariff (about £45 p/m) which gets 750mb which hopefully I wont go over - checked my data usage today, nearly 10gb since August '08.
Still would rather it was unlimited tho so I didn't ever have to even think about it. Even tho every single network (carrier) in the UK now has the iPhone it hasn't made prices any more competitive.
Now just waiting for handset prices to be released. Am hoping that I'll be able to pick it up for free although I may need to get a 24 month contract for that, so most likely I'll try and stick to an 18 month contract and hope the handset price is similar to how the 3gs was on release, about £60 for the phone ($90 ish).
Really looking forward to this phone now
