I do not see option to go back to the previous view in iPod version like in PC version. It is very inconvenient to jump to hiperlink and have no ability to return back. I found out that this question was already asked in http://forums.adobe.com/message/4060734#4060734 on Dec 2, 2011. But yet there is no any feedback on this.
It is long overdue to implement this feature in the software.
Mobile enviroment put particular emphasis on being able to navigate conveniently within the real estate of the screen of mobile device and within a narrow scope of commands.
It is a pain to click a hyperlink to jump withion a document and then manually scroll back or remember a particular page number where you jumped from.\
Ir can be implemented as gesture.
