Will FaceTime be available over the data networks with ios5, or will it continue to be wifi only? Also, with iCloud, considering I'll only be using it to sync my contacts and calendar, how much data is it really going to consume? I can't see it being too much? Reason I'm asking is that my current unlimited data tariff has come to an end. I can save almost £15 a month by dropping down to the same tariff but with a 500MB data allowance, or save £10 a month by dropping to a 1GB allowance. I'm wondering whether I should continue to pay more and have unlimited data? Will anyone really need more then 1GB a month?!
