I bought a cellphone from the retailer called the mobile store and after some days my mobile started going blank i had to call my friends after every 2mins when i went to this retailer he gave me the wrong address to repair my mobile and when i came back he gave me another address and i had already wasted behind this stupid mobile phone i want my phone replaced as soon as possible and i have never seen a retail bill without a telephone number Sony Ericsson is disappointing the cust by selling defective piece in the market so will never recommend for such a mobile.
