For the next two days, December 13-14, 2011, you can download the New York City – City Guide app from Lonely Planet for free. (Thanks to GalleyCat for mentioning this limited-time offer.)
To get the free NYC City Guide from iTunes, download the Lonely Planet Travel Guides app, if you don’t already have it. Open the app, find the NYC City Guide in the menu, and install it.
The City Guides from Lonely Planet include maps you can view on your phone while it’s offline. If you’re a foreign visitor to New York, you won’t need to use your international roaming data plan to get un-lost.
Thanks, Lonely Planet!
