Gowalla has released an update to its social location sharing app for the iPhone and iPod touch, adding support for iOS 4 multitasking and adding new high-resolution graphics for the iPhone 4 Retina Display. iOS 4 improvements include support for Fast App Switching and continuous tracking of nearby spots as well as other improvements in how Gowalla handles location tracking.
New users can now sign up for a Gowalla account directly within the app, including the ability to fill in information from the iPhone Address Book and the update also improves the process of connecting to Twitter and Facebook. Gowalla 2.2 is available from the App Store as a free download.
A separate iPad version is also available.
