Well, I actually got this phone about a month ago - So I basically put some of my thoughts on this phone : )

To me , this phone is something like upgrade of Nokia 5800 XM. It share the same OS with 5800 as well as most of the interface in the phone like messaging and web is totally same.
However, It just partially upgrade on making the phone smaller as well as better camera/video quality.Through 'lowyat' forumer, It says to be cheaper version of Satio

On term of sound, It totally bad . Worst then 5800 XM totally. At first, it doesnt even have equalizer to be in with . Have to get it through Playnow® <---i forgot the code for 'tm' On the good side , it doesnt 'hang' as frequent as 5800 XM . 1 of its main feature is invulnerable to scratch .

This Phone is great in taking sunlight picture





But not as good for indoor pic



Summary of the review

-Great processor Speed - less 'hang'
-High picture quality - 8.1mp
-HD video recording (720p)
-Bad Sound Quality
-Low Internal Memory : (
