BlackBerry time again

My old BlackBerry started developing some interesting new habits - namely you would click on one option and it would jump to a different one. This meant that it constantly wanted to make an emergency call rather than unlock, deleted emails rather than reading them and other enormous fun. Anyway, got a whizzy new one now with GPS (neat), and all sorts of other features that you will never use. 

Actually the GPS is rather clever, now I've worked out how it works. I asked it to tell me where I was and it was spot on. Looking at the options, there was a "local search", so I typed in "pub" not expecting it to be intelligent enough to recognise anything quite so useful. Gosh, it came back with a list of the ten nearest (seven within less than a mile - this is England) and it shows me where they are on the map. I am almost impressed. 

Of course, being a geocacher I actually want to put in some coordinates and be directed to that place, so I have investigated bits of GPS software for exploiting the built-in GPS. Unfortunately the ones I have found so far assume that I live in the colony the other side of the pond. They also, as far as I can make out, lack that nice simple function - tell me where I am and let me enter some coordinates of a place I want to go to. Doesn't seem a lot to ask? If anyone knows of a simple, intelligent, useful, non-monthly subscription piece of GPS/geocaching software for the BB, please let me know.

The other problem is that it doesn't work! Emails are fine, but appointments are useless. If I set up synchrnoisation to Outlook I get a message about the appointment, but no option to accept/decline/tentative or whatever and it only synchronises when I attach it to the laptop - useless. When I choose wireless BB sync, I get the entries in the diary but no invites and option to accept/decline etc. What am I doing wrong? Or rather what are the manufacturers doing wrong? 

Last but not least, just read an article about people using BBs, phones, laptops etc. when someone is presenting. Should this be banned, or do I simply assume that because I am such an incredibly engaging, fantastic speaker than the problem won't arise?!
