Help Storage and Memory


I have bought a Cambridge Starpad branded as wm8850. It has 2 gb of what the tablet is calling RAM and 6gb of what is called SD Storage. I can't seem to install apps to use the 'SD' storage and the initial 2gb is filling up fast. Unlike my phone there seems to be no option to move apps onto the 'SD' storage. IS there any way to use this 'SD Storage' as a default. Thank you.

Thank you

PS The tablet is runnng ICS. Thanks
