Jabber support for iPhone, iPad, and iPod touch is limited to the current Apple Store versions.
Cisco Jabber for iPhone and iPad is currently supported only through the Apple Store. Once Cisco Jabber for iPhone and iPad version 2.1 is available, the old versions will be deprecated. Any Cisco Jabber release is evaluated against the current version when a flaw is discovered.
There is no difference between Cisco Jabber for iPhones and iPads downloaded from Apple Store and Cisco.com as far as this policy is concerned.
