It's never been rooted and has always run on the ROM it came with. It's been updated to Android 4.0.3.
Being an Australian model, it comes with Navigon (brilliant GPS navigation app, which has maps for both Australia and NZ), and a couple of other extra apps that aren't offered to NZ. More details here: More details here: http://www.samsung.com/au/smartphone/galaxy-s-2/index.html
It has its original box with everything it came with. The earphones & buds have never been opened.
Included with the phone is a black Otterbox Commuter Series case (value $49) and an unopened Zagg Invisible Shield screen protector for the SGS2 (they are USD$24.99 + shipping).
The phone has been absolutely flawless and I'm sorry to see it go.
If you are interested, message me. I'm looking for $450 for this package.
