Tom Tom Go for IPhone update

Hi guys I just wanted to let you know that the app for tomtom on the iPhone has just done an update and the 2 main features are .
1 power saving mode which switches the display detail down to a low level which for me isn't an issue as I have the phone in my pocket and just use the audio which is plenty good enough and I haven't missed a turn yet just because I couldn't see the screen.
2 winding roads is now included in the route planning which is I guess taken from the tomtom rider so that's brilliant and I can't wait to use it, I have tried planning a couple of routes with it and it really does take the winding roads .
Overall a couple of great additions to an already pretty good app so I just thought it was worth giving you this info cheers.
