I've an iPhone 4 on Three's One Plan, and it's coming up for renewal. Although the free minutes and texts are good I use the phone mainly for data including the personal hotspot feature for my MacBook Pro when I'm out and about. Any suggestions for a good iPhone5 deal for me? ps. I always get stung on 0845 calls to customer service numbers from my mobile. Does any deal include them as part of the plan? pps. Access to BT OpenZone as part of the deal would be cool too but not essential.
