I have been using the Nokia Geocache navigator ever since I got my Nokia N85 around 7 months ago, and think that 15 euros isn't that expensive, and would purchase it, especially if it were an improved version.
However, in those 7 months, I have had my phone replaced twice due to various reasons. If the subscription is only good for the life of the handset, does that mean that if I purchased the new Geocache Navigator tomorrow and I had to have a new phone next week, then I would then have to pay for it again? And would I then have to pay for the full 30 euro version instead of the 15 euro upgrade? This to me is completely unacceptable, and if this is the case, then I have no option than to look for alternatives.
