You need to tell us what you are looking for in the phone and how much you're going to use it. various factors will come in to play such as accessories, colour, networks, on-board memory, battery life and the like.
I suggest u 2 buy NOKIA phones.The current models like - 2300 , 3100 , 3530 or 7210 are coloured screen phones and loaded with latest technology.Offers u 2 access WAP , music , InfraRed etc.And all under ur budget..!
