Before i put in my 30 day notice (my contract ended on the 30th May anyway), they did offer me my same contract for £5 more a month. I was paying £35 a month, so i wasn't going for that. Even said to them why should i pay more for something i currently have, why can't you renew at the current price?. They couldn't give me an answer, so i left.
Ditto, moved to o2. They've got good coverage, and i get auto-connected to their Wifi. Got my old EE deal on the o2 contract, which is good.
