So, some good has come from the Icelandic volcano eruption that has caused chaos for European travelers, as Lonely Planet have decided to cut the price of all their City Guide iPhone applications from £9.49 to absolutely zero!  This offer has been in place for a couple of days, but you still have a chance to grab the apps, as it expires at 11:59 (GMT) on Thursday 22nd April.

As one would expect from Lonely Planet, these apps are pretty special.  Based on extensive research, they offer location aware, interactive maps which can be used both online and offline, a mass of images, points of interest, reviews, travel information and the option to favorite places you must visit.

The cities covered by the Lonely Planet Guides include:

• London
• Paris
• Rome
• Vienna
• Moscow
• Amsterdam
• Munich
• Vancouver

There are several others inside the App Store too, so take a look around and grab whichever you need ready for a future holiday!
