I'm not sure if anybody has gotten around to reading "Designing for Touch" yet, but I imagine there would be a wealth of considerations discussed in this book: https://abookapart.com/products/designing-for-touch
It is a familiar pattern to see the menu in the top left, although it isn't ideally placed for right handed users (the majority), who use the device in one hand. As with most things there is an element of "it depends", what other elements are in the interface? Do you need a "Back", a "Cancel", a "Done", if you are designing an app UI then these requirements could dictate the placement.
A post worth reading which relates to placement: http://www.lukew.com/ff/entry.asp?1649
Something that you also should consider is whether a hamburger is the best solution for you. There have been a wealth of posts which relate to how poor hamburger menus perform, including this one: http://www.lukew.com/ff/entry.asp?1945
Finally this post is worth a read: http://exisweb.net/menu-eats-hamburger - if you cannot avoid hiding some options behind a menu then perhaps it would be wiser to use language, rather than iconography.
