OK, the N80i is not supported. I hope the N93 is supported! Sorry about those having comment problems; I need to upgrade to Drupal 5 to fix it. Soon!
You won't need to wake the GPS antenna, ShoZu will do this when necessary so you don't need to do any more than pair the device. What you will need, however, is a very strong GPS signal. ShoZu will wait until you have signal from 5 or more satellites before tagging your images because any less than this can produce inaccurate results. You'll notice sometimes on weak signal that your navigation software will jitter for a moment, if we tagged images at this time they would be way off. So please make sure you don't just have signal, but you have a very strong signal. We've done this because we figure geotagging is no use unless it's 100% accurate all the time!
By the way Roland, the N80i is not supported as yet and there are a lot of memory issues on this phone so just be weary of this also. Tried to post a reply on your blog but it had an internal server error and now I'm listed as a spammer and it won't let me post! Now's the time I finally get to ask you for support :-D
