I thought this is a great contract for this phone (for someone who doesnt need loads of minutes and texts, and only wants a short contract its ideal)
Get the brand new Samsung U900 on T-Mobile Flext 25 (12mths, £25P/M) with 7 months half price line rental (-£87.50)
Contract Term Cost - £212.50!!
Also go through quidco for an extra £20 back. BMP.net are very reliable, I have been with them for 18 months, and have got the cashback on all 5 claims easily, no chasing them up, very easy.
