I have a deal with 3 for the samsung galaxy note which I think is good, no upfront cost and 2000 minutes, 5000 texts and
unlimited internet. for £38 per month.
Just got mine today! Phones4U had O2 200 minutes unlimited texts and 250mb data for £21.50 with free handset and I got £50 cash back through quidco. Also the phone was unlocked and unbranded. The data is a bit light but Mrs finbaar is having that sim.
Absolutley the best phone around for ME. I use it for surfing and nothing comes close. Superb screen.
