guys i have started a blog which contains information about phones wallpapers,reviews etc.Do you guys think that keyword phone will bring me traffic to my blog so what you guys think of my blog here is the link to my blog http://phoneapp.blogspot.com/
Your title is too broad, and your keyword too general. You should zero in on a specific key phrase, like cell phone reviews, or specs. You need to be specific about what your blog is offering. You also need to look around...that is a very competitive market with 100 million dollar companies competing for the traffic. if you are going to get a piece of it, then you should spend more time on design and content, and not just your adsense placement.

You need to change your title so its not to general, Also I would move your google adds to your header because its just off putting in the middle of the page. Finally I would rccomend a variation to your posts, because all of them have 1 small photo and 1 page of writting. Spice it up a bit
