Fixed! Thanks

Love it again! I've missed this app since it's trouble with os4, but it's back in the saddle again. A few bugs..but it's free and enjoyable. Thanks

Great app - 2.2.2 works with OS 4.1 and fixes many bugs

This is a fantastic app - very useful in a number of settings. The new version (2.2.2) now runs smoothly in OS 4.1. It also reads the location services from the iPhone GPS automatically for new locations. The developer has also fixed many small bugs, and this program once again lives up to it's promise. Really great for people who need detailed information about the sun angle, rise & set times, day length, equation of time, etc. - e.g. folks who work, teach or play outdoors and need to know where and when there is sunlight. Works around the world and at home - excellent app, and free!

There is nothing that this VERY INTERESTING APP does that precludes the iPod Touch 1G .... yet for some strange reason, the creator has seen fit to exclude this model. .... I emailed a few days ago asking about, this but as yet have no answer. I would be very happy to revise my review and rating if this app were updated to allow usage on the iPod Touch 1G. I am so very interested in using this app in the various places I travel to. Please update it (I am hopeful that the low version number means that this app will be under further development). Thank you!

p.s. perhaps many of the one-star ratings are from other hopeful iPod Touch 1G users who were as disappointed as I was when I tried to install it.
