I want to buy a mobile phone. But I am not able to understand which mobile phone to buy and which not to buy. One of my friend told me that acer DX 900 SMART is the best phone. I have searched the features of it on internet and found that It is really a good phone, But I want the opinion of that person who is using this phone. So Is there anyone who can give me acer DX 900 SMART review?
