I am looking for startup smart phone, I have short listed Samsung Galaxy Y, Sony walkman and HTC explorer, please suggest me which one is better. In terms of budget , I don't want to spend much, infact the lesser is better. If you have any other phone in for suggestion in lowest or entry level phone then please suggest. Also please do not suggest cheap Indian brands like Micromax, Maxx mobile , karbonn etc. because I only want to buy from established brands.
