Rather than making a new thread i just put my question on this one,

Given Nokia don't "support" host mode, it'll have to be some kind of adapter if you want to charge the N900 and power an external device --Jaffa 16:26, 2 September 2009 (UTC)

please elaborate this for me... so is this mean N900 cannot open usb flash drive?

jaffa also mention in N900 wiki that there is no digital compass on the N900, because i'm new here i dont know who jaffa is, so is he a nokia representative?
