Once again, it appears in the code snippet of iOS that Apple is baking something in iOS with iChat features. It appears that Apple has been working on an application to integrate iChat into iOS, or already they have finished the work at their end. The developer John Heaton over twitter has unveiled the couple links of the iOS code represents the iChat functionality in iOS.

It is highly expected by the developers that Apple might be working on iChat application for mobile device to merge the iChat of Mac OS X with the latest iMessage service of iOS 5. According to the developer, the code is present in the iOS 5 SDK, since the first public launch of the iOS.

It’s not the first time that we are hearing about the merger of iChat with iMessage. Firstly, we have heard about that in the earlier week of September, before the launch of iOS that Apple has been actively working on iChat to merge it with iMessage.

The news arrived as the site found various strings relating to “instant messages” in the software framework of OS X Lion’s iChat client. Dubbed “timeDelivered” and “timeRead”, the site noted that both strings found appeared to relate to the active “tracking” of delivery of instant messages.
