Root [T-Mobile] Galaxy note 2 storage

I have a Note 1, which has been great, but I keep on running up against the limitations of the 2Gb "device" storage. I have decided to upgrade, but can't currently afford a Note 3. I want to check if the Note 2 will work for me.

Please can someone confirm whether the local storage is split into "device" and "sdcard" like the Note 1, or unified like the 10" Note tablet. Also if it is split, how much is "device" storage for programs etc?
