We previously discussed the fact that Trillian was sitting in approval limbo with no word from Apple as to why the app was being delayed. As of today it is available for US$4.99. Cerulean Studios website has more information on features, and we will be reviewing the app soon, but we wanted to let you know that it was available (for iPhone/iPod touch devices running OS 3.0 or later).
Second, the 2.0 update to Google Earth for iPhone [iTunes link] is rolled out now. The major new feature in the app is the ability to overlay your own custom Google maps onto the geographic display in GE; the app also improves POI selection and adds a slew of new languages. Google Earth requires iPhone/iPod touch OS 2.0 or later, and it's free.
