mobile phone contract renewell help

my contract is going to be up for renewal in just over a month and i was thinking of getting a samsung s5200, just wondering if anybody has had any experience of this phone. also feel free to recommend any other phones, my criteria is a good battery life and a reasonable camera. i generally use a mobile to make calls and send text messages so a smart phone would be overkill for me as i wouldn't use the features.

i was thinking about going over to the orange raccoon tariff as i tend to make more calls than text messages, when they state unlimited land line minutes is this really unlimited or is it like bt were the free bit only last an hour then you have to hang up and redial to carry on the conversation for free.
