I have bought a Mobile on-line with Flip kart.com the delivery was as per its schedule. but when I got that mobile. I have started to use it. for 10 days it worked correctly now I am facing lot of problems with internet connections, when I asked with airtel everything was fine from their end. problem is with the handset really it is a worst mobile I have never seen. I facing lots of problem Like when I charge the mobile it will get heated, if you talk for a long time it will get heated, so I request all of them not to use this type of mobiles. VERY VERY WORST MOBILE HANDSET.
