Gameloft have released Brothers In Arms: Hour Of Heroes for the iPhone, bringing 14 missions over 3 theater campaigns to your pocket.
Control is via a 'fire' icon and a touchable movement circle, that at least looks like it might be a bit more analogue than a fake D-Pad and which changes according to whether you are on foot or in a vehicle. The accelerometer comes into play too as a natural way of lobbing grenades at your foes. (Be sure to hold on tight, lest you lose your precious phone)
During the 3 campaigns in Normandy, Ardennes & Tunisia you will use bazookas, machine guns sniper rifles and grenades, drive a Sherman Tank and a Jeep and die in a hail of bullets. A lot.
