to mostafa samir: dear dude, there are many ways to connect to internet, use a free wifi once to installl or use ur SIM card GPRS to reach internet, if u donot have access to wifi or GPRS of your sim card (which in unusual), just borrow some friend's sim card or go to a internet cofea to use wifi anyway if u cannot figure it out how to connect to internet, just leave installing programs like this bz u really need more basic information? As some buddies said it's usefull but not completely necessary and they explained how to use the replacement. Anyway this is a very nice shortcut passage that make it easy so I admire it, use it, u won't be regret, enjoy guys. U know what makes me happy whit N900? bz it's endless for new programs and more development. never u can say: that's it, i'm done with installing all i need, there'll be coming usefull stuff like this!
