Good to see the contract deals already appearing for the upcoming Apple iPhone 5s and iPhone 5c. But not good if you want yours with 4G connectivity.O2 is first out of the blocks, a company that has done good business with the iPhone from day one. It's probably hoping to do the same with the new models too, but it seems to have an initial problem with 4G, which might impact on pre-orders.According to O2: 'iPhone 5S and iPhone 5C are both 4G-ready devices that will be enabled to run on our 4G network within the coming weeks – this will happen when new settings are ready to be sent by Apple and we will inform customers when they are available.'So both phones are 4G compatible, but we just don't know yet when that will be turned on. We'll let you know when that changes.In the meantime - and knowing that a lot of the UK isn't able to hook up with O2's 4G network yet anyway - you can still order the new iPhones via O2, with orders kicking off tomorrow, 13 September 2013.Deals are on the Refresh tariff, which splits tariffs from phone prices, allowing you to pay off your phone if you want to upgrade.If that appeals, you can get an iPhone 5s 16GB with unlimited texts, unlimited minutes plus 1GB 3G data for £37 a month if you pay an upfront cost of £119.99 for the hardware. For 4G, you can get unlimited texts, unlimited minutes and 5GB 4G data for £47 a month, with the same £119.99 phone charge.If you want to go for the cheaper iPhone 5c, you can do just that. The iPhone 5c 16GB with unlimited texts, 600 minutes and 750MB 3G data is £32 a month with a £49.99 charge for the phone. Again, there's a 4G deal, with unlimited texts, unlimited minutes and 5GB 4G data for £42 a month with a £99.99 charge for the phone.The line in the sand is drawn. We'll see what Vodafone and EE plan to do in the coming days, no doubt.
