One to add:- locaTags | Location sharing for BlackBerry
locaTags lets you share your location - and what you're doing - from your BlackBerry...
* Tag the places you want to share (eg. Home, Office, Bob's House!)
* Say what you are up to or how you feel (eg. Watching TV, Working or just hanging out!)
* Automatically share on the web - via RSS, Fire Eagle, Facebook, Twitter, Skype and more!
Let your friends know where you are and find out where they are personally, automatically and securely via your smartphone.
You are in complete control of what your friends see, "At home", "Office", "Playing Soccer", "Walking the dog", "Surfing", "Yoga" etc. If you haven't named a place your position will just show up as "Unknown". and you can always "Go Dark" if you dont want to be seen.
If you want, you can add additional location information like zip or post code to a favourite place so FindMe can show your friends a map or directions to where you are. Great for organising impromtu parties or raves
FindMe works with all trackball Blackberrys. It does not require GPS or additional hardware.
Only your last named position and the time you were there is shown. No information about your location history is stored or recorded. locaTags | Location sharing for BlackBerry
