Thanks for your comments dudes Actually it has still lot of bugs inspite of many updates, especially it's not working with all networks, very choosy i mean! It's suppose to be a greater function rather than other phone brands but if eveythings go well it'll be the same as other phones which are easy in setting and compatible with all different types of networks. Briefly, in a golden situation it does the same thing that other phones do easier and less time spending! Let's wait for a nice version of this program without bugs and with a easy setting configuration. I'm counting seconds till then. I gave 1/5 for this version totally by the mean of compatiblity and easy set compare to the other great functions of this tablet phone. Just for a moment you compare the ability of N900 in SMS with other phones, its really great and multipotential job. THEN IS IT FAIR TO GIVE THE SCORE OF 5/5 to these two different ability? of course not. so I give 1/5 but I'm waiting for a surely coming new version WHICH WILL DESERVE 5/5 and i'm sure about that. i'm crossing my fingers!
