There are seven background services that will be allowed
, and which shouldn’t significantly affect the performance of other apps:
: i.e. Pandora can play in the background and popup controls can control it.
: Skype calls will continue if you need to switch apps; a “return to call” button will show, and you can also receive Skype calls on a locked phone.
: turn-by-turn directions can continue when you leave the app. Music can run at the same time and will quiet down when directions need to be said. Very slick. Uses cell-tower-enhanced AGPS. A notification will show in the status bar if an app is transmitting your location. You can also turn off location app-by-app.
: the same push notifications you know and love.
: in-phone notifications for, say, pop-up alarms and such. Local app stuff.
–Fast app switching
: this is the service by which apps can store their state when you switch to and from them.
: allows, say, a Flickr upload to continue if you close the app.
