sony Xperia z1 and htc desire

Description:

I have a unlocked htc desire and a Xperia z1 I think it is, I say that as I hardly use it. Both in good condition however I don't have the boxes due to a big move, plus I only have the charger for the htc but it works in both phones. I'm looking to swap them for a Nokia lumia any model apart from the 520 if possible.
