Nokia released the Here Maps app for iOS devices. You can use as a turn-by-turn navigation, search for interesting places, buses and plenty more for free. This is how you install it on your iPhone or iPad.

Google by far isn't only a search service or an e-mail provider. I will introduce you to their Google Docs service which you can use as your very own office in the cloud.
