Padfone 2 connector has died, so its time for a new phone. Id say upgrade but dont have the money for a s4 : (

I thought about getting the s3 mini.

But then I saw the s4 mini duo which would be good as my new work phone is a windows phone which im not liking (cant change the keyboard?!?!) and I dont need anything too fancy. Would save me having to carry 2 around.

Basically my phone is on 2degees, and the work phone is on telecom, will I have any issues getting one of these phones?
Has anyone else heard anything about these phones? Ive found a lot on the s4 mini, but not the duo.
I have no intention on moding or anything, just for basic use.
