With the iPhone exclusivity to O2 drawing to an end, Orange have already confirmed that they will begin selling iPhone 3GS on contract later this year. This is great news for Orange users in the UK, with Orange having the largest covering area to support 3G across the UK.
Orange is fast becoming one of the most popular mobile networks in the UK with their low price calss, texts and especially their 2 for 1 Wednesdays offer, which has been a god send in this current economic climate to help people afford to go to the cinemas.
If your an Orange fan and your an Apple fan, register your interest now!

This is also great new for Apple, when O2's exclusitivity 2 year contract is up this year, apple will be able to branch out to a larger portion of the UKs market share in UK telecommunications. This could also be a larger portion than they first intended with the new merging of Orange and T-Mobile to create the largest UK market share holders for telecommunications in the UK.
Unfortunately Orange hasn't specified any details on contract prices but we can be reassured that they will keep them as low as possible to go to price wars with O2, so hopefully the merging of Orange and T-Mobile take place so they own a larger market share and can reduce the price of the contracts!
Hopefully we could see an Orange 2 for 1 Wednesdays app making it's way to the app store in the near future!
