It's a little too generic looking for me. Your content is really good, but the design is bringing the quality of the site down. You should play around with different themes and styles (try to stay away from the blue & white colour scheme). I'd also recommend you get a logo designed, or if you're confident, design one of your own.
i like,the ads fits well with your site,i just think that you should put a margin space between the images and text
The categories section could do with being seen wehn you first load up & made a bit more obvious so people can easily find what they want straight away
i agree. There are lots of mobile phone review sites and make yours unique but not fancy. Best of luck!
Very nice site, the adsenese at the bottom of the page isn't worth it though, mix it with your content a bit more.
