I currently have a Nokia windows phone. Not sure of the model but it's a couple of years old and my dds inform me it's a bit rubbish 
I'm not really into having the latest devices etc but current phone does seem to be on its way out plus the camera is terrible (no front camera and takes a picture about 10 seconds later).
I'm on a SIM only contract with Tesco till April so I thought I would buy a reasonable second hand phone and continue on the contract.
Dh and my dds have iPhones so that's a possibility. But I quite like the windows layout of the nokia, is there anything similar that's a bit more up to date?
