Knowing he owned a Nokia N86 and iPhone, I arranged for Nokia Creative guy James Burland to get a review Turbocharger 3400 from Proporta - this is the revamped device, not the original white one I reviewed two and a half years ago. As it happens, James has published the review over on All About iPhone, so go read it there, I too can vouch for the usefulness of the bigger Proporta charger.
