If you are due an upgrade with O2 & want a Galaxy Note 3 you can do this through Phones4U. I ordered mine last night. My o2 contract ran out in August & was holding out for the Note 3. They had a couple of O2 contract options. I chose, unlimited calls, texts, 1GB data & £99 for handset @ £32.00 p/mth. Dunno why it's taking them so long, Iphone was luached yesterday & it's already on their site. Anyway, hope this helps.
