Guys, I thought this may be of interest to a lot of you so thought I'd start a new thread so info doesn't get consumed in the other UK iPhone thread I just got off the phone to T-Mobile on an unrelated call - basically I don't check my monthly bills (naughty) but I did the other day and realised that T-Mobile had not been deducting my discount for not upgrading my phone last year. I spoke to the guy about getting a discount off my current Flext 25 & W+W. He said he can deduct £10 off which would cost me £20p/m. But the odd thing was that if T-Mobile were to upgrade my phone with a free Samsung Tocco they'd be able to give me the same tariff for £17p/m - a discount of £13p/m!!! Strange or what??? Anyways, to get to the point, finally, I asked if I could then get a sim free iPhone 4 from Apple and use the sim in that rather than the Tocco and he said "yes". So, if they do give me the discount, would I also be better of with the Flext 25 & W+W? Or should I go for this https://www.t-mobile.co.uk/shop/mobile-phones/sim-card/pay-monthly/ WITH a Booster of Unlimited Internet?
