Looking at the Carphonewarehouse website and I noticed they are doing deals on the HTC range so I had a look at the Incredible S and worked out that for £389.99 (without any cashback) you get:
Phone with 200 minutes, 1000 txt, 1gb data
For an extra £10 over the year you get 300 minutes
And for only 409.99 over the 12 you get 400 minutes.
Plenty of other deals on there worth checking, notice these prices seem to be lower than yesterday on all talkmobile contracts.
Still holding out for an S2 but the low o2 price may be having a knock on effect.
