Lonely Planet Publications Pty Ltd has their Melbourne City Guide (iTunes Link) in the iTunes App Store for FREE (regularly $5.99) for a limited time.

Melbourne’s our home town, so you can bet we had fun retooling our flagship Cityguide to make the most of your iPhone. This is a city that offers its many pleasures unobtrusively. Without a good guidebook, you stand to miss most of them, and quite simply, this little baby has it all: hundreds of independent, in-depth reviews of places to eat, sleep, shop, see and socialise; interactive maps offering comprehensive coverage and GPS plotting the laneways and villages that give this city its charm; and lavishly-rendered images to really paint the full picture.

All Lonely Planet iPhone City Guide apps give you our tried and true guide information, enhanced with iPhone-smartness, all in the palm of your hand. Read up on the city, see the sights and things to do right around you, and look at our handy offline maps without worrying about data roaming fees. Finally, a guide you can carry along in your pocket!
