I have just purchase my first Android phone a Desire from Hong Kong and am now using it here in New Zealand where it is yet to be released. I have a query about how many apps I can run at once and what I can do to stop an app running. Given that android is a multi-tasking O/S, my understanding is that I can start an app, go back to the menu and then start another app and pretty muck keep repeating this process. How then do I go to the earlier started apps and actually stop them running so they are a) not consuming systems resources and b)not going out to a data network using up my tellco bandwidth and therefore increasing my bill? Any answers or help appreicated. Also is there a skype type solution for my phone as I understand that skype now runs on the iphone.
