UK iPhone applications developer Coolgorilla has launched a London Travel Guide for the iPhone. The guide includes ground and aerial video footage, embedded maps and touch-to-dial telephone links, together with a 200-page travel guide in one, easy-to-use download, available from Apples iTunes and App Store portals.
One downloaded to the phone, the guide does not require a data connection, which means that users can access the guide while on the underground system. There are also options for the user to make use of the iPhones connectivity, with hundreds of Google Map and web links all of which are optional and clearly marked out. 
Editorially, the London Travel Guide covers over 50 of Londons major attractions along with restaurant reviews, event listings and transport information. Theres even a section on cockney rhyming slang.
The London Travel Guide is available to download from iTunes for $1.99 (1.27) and Coolgorilla says it is already working on similar travel guides for a number of other destinations due for release later this year and in 2009.
