Just though someone may be interested to know that t mobile are selling the samsung m110 though phone for £20 (well £19.56). When the gadget show reviewed this phone it took everything they could throw at it and more, it even survived tests that destroyed the jcb tough phone that costs the best part of £200. So perfect for those situations out in the wilderness that a normal phone would not survive. I know I'm getting mine.
