I have an I pad 2 and I need to update but can't see software update option anywhwere
Assuming your Tag shows the correct iOs version you have on yur iPad (4.3.3), then you can't do it on the iPad.
The over the air update option is only available.from iOs 5.1 and later
To update earlier versions you need to connect your iPad to a computer running iTunes and perfomr the update from there.
