released on September 15, 2006. A Google Talk client was also available for BlackBerry devices from the BlackBerry site. Google Talk support was also integrated into Google Android devices, but did not support voice and video calls below Android version 2.3.4. This was released in April 2011 for the Google Nexus S. However, given that Google Talk provided XMPP protocol, most mobile phones for which a suitable XMPP client existed could also offer Google Talk service, at least theoretically (depending on the handset, the user may have encounter security warnings because of unsigned Java ME MIDlets or limits put in place by the mobile service provider). Mobile clients specially designed for Google Talk existed as well. Most phones supported the IMPS protocol, and there was hybrid XMPP/IMPS networks (through XMPP transports, or specially designed hybrid servers), which could also contact Google Talk users. The Google Talk service itself was unusable from IMPS (that means, one could not log with their Gmail account, but they could talk with their Gmail friends with their IMPS account from their mobile phone). For most smartphones, including Symbian-based as well as Android, third-party applications such as Nimbuzz and Fring included support for Google Talk accounts, including VoIP calls. Text formatting Google Talk did not provide the user with a menu for text formatting. Nevertheless, Google Talk did support some text formatting features like making text bold and italic. To write a message in bold, a user could type the required text between two asterisks (*), for example, *this text would be bold in Google Talk*. Similarly for making text italic, one could put text between underscores (_) and for strike-through in text content, one could put text in between dashes (-). This only functioned in some of the Google native tools, and did not always function as expected when received from other XMPP clients. History 2005 On August 22, 2005, The New York Times reported a rumor of a Google-branded "communications tool" service and the Los Angeles Times provided details. Subsequently, the subdomain was found to have an active XMPP server. Two methods of logging into the server were discovered soon after and the ensuing response by eager bloggers revealed to numerous others how to log in before the official release by Google. On the evening of August 23, many logged-in users using port 5222 to connect were disconnected and unable to log back in.
