Everybody makes mistakes from time to time, and it seems that even a huge company such as Apple is no exception to the rule as well. Apparently, in what has got to be a very rare slip-up from the Cuptertino giant, Apple has somehow managed to publish the buggy and unstable test version of the Google+ social networking app onto the iTunes App Store instead of the stable version that Google had originally submitted.
Have you downloaded Google's Google+ social networking app onto your iPhone yet? If so, you might want to head down to the iTunes App Store one more time to confirm if the copy of the app you have installed on your iPhone is the correct version, especially if your current copy does not seem to work as advertised. This is due to the fact that Apple has somehow managed to publish the test version of Google+ onto the iTunes App Store instead of the stable version, which lacks the stability and functionality that the finalized build sports.
According to a Google+ posting made by Google+ Mobile's lead product manager Punit Soni, the search giant was alerted to the issue and has since pushed out an updated version of the app which reportedly fixes all the issues that users have been complaining about in the test version of the Google+ app. This updated app sports the version number 220.127.116.119, so you should be able to tell if your downloaded copy of the Google+ app is that of the test version by simply comparing those version numbers.
Last but definitely not least, Soni has also confirmed that the Google+ app is currently incompatible with iOS 5, although he did mention that Google is working to implement iPad compatibility into the app, and that such a feature would reportedly be "coming soon".
