The iPhone has a big problem; It doesn’t allow applications to run in the background (with exception of the iPod application) . Now there is a fix!
Quoting their blog:
“Several people have asked us about their always-on presence option even when fring is turned off, so here is a communal explanation for y’all:
The new Always-On feature keeps you logged into fring even when the fring application is closed on your iPhone/iPod touch.
It works like this:
To activate the Always-On add-on, click on ‘More‘ –> Add-ons –> Always on.
How do I get the notifications?
To get the notifications in real time you should have your email address configured to be “pushed” to your iPhone/iPod. Once you got that done, you’ll get an email whenever someone’s trying to call/chat you. Just open the mail and click the link –> fring will open up on your phone and display the message.
If you don’t click the link within 5 minutes – we will log you off from the Always-on service and won’t send you more notifications until you log in again to fring (we don’t like spam…)
Currently this feature is available for UK and US users only but no worries… we will gradually make it available to all countries.
