It appears that the latest version of the Apple iPhone and iPod software (2.2) breaks the current release of Fring. Currently Fring users who have updated are finding they can no longer connect to the Fring servers. I’ve been wondering for quite some time if Apple doesn’t syphon all IP traffic through a central hub, then off to the internet, but it’s just my own head. The reason being that Apple could control malicious software if they controlled the iPhone and iPods in this manner.
In anycase, Fring on the iPod and iPhone currently is inoperable. I wish the dev team luck in finding a solution. I even ordered a mic for the iPod in order to use Skype and/or Gizmo (currently only 1 VOIP server can be used at a time) with my iPod. So, it appears I have to either deprecate my phone (may be very difficult to do), or hope that Fring solves this quickly.
Here’s a thread I came across on Fring’s forums describing the issue: iPod Touch and version 2.2 issue.
Update! Fring says they have a fix and it should hit the AppStore soon! Excellent. (See Above Thread on the Fring forums.)
