                  Are you buying a new mobile phone? For about five years now, the question for smartphone buyers is still bit confusing.  Answering that question is more difficult than ever.
 There are many choices around there and it all depends on the features you want. Either way, today's mobile phone's become smarter and it almost replaces your compute

                 The choices are Android, Windows Phone 7, iPhone / iOS / BlackBerry and Symbian OS platforms.

So, Below is a small comparision table for Selecting a Best Smartphone

BlackBerry OS 562.58.5
The iPhone OS and Android emerge out as the clear winners. Its tough to decide between them, but you can’t go wrong with either of those two. They are both intuitive and well designed. Windows Phone 7 is the new kid on the block to watch out for. It presents a completely fresh, new interface that is great at getting things done quickly, and should appeal to a large segment of users looking for no-nonsense phones.
BlackBerry and Symbian are solid operating systems in their own right, and have large (and loyal) user bases. But in an objective analysis they tend to fall behind a little when compared to the best-in-class. They will need to ramp up their game a bit (which they do seem to be doing with their latest versions), to stay among the top contenders in the long term.
