I also agree...... why did nokia change from their commonly used previous power plug? if they wanted to gain size and make more compact using the usb plug would have been a better choice, and the previous plug wouldn't have been so much place taking.....
however if we can put the usb into host configuration then it means that we can 'wire' the 5v usb to the internal 5v, hoping that the design allow to feed the internal vcc core (ie not a dedicated regulated 5v, but the vcc core derivated from it)
will give a try
