On or off contract? What carrier?
Not in the US so no contract. Now that I'm looking some more I think the LG Optimus L5 II might fit the bill as well.
This is really just her first smartphone, anything that takes good pictures and has a decent screen resolution should do fine, unless it has some glaring quality issue or things like that.
I like Sony because they're easy to mod, my dad's running CM 10.2 (Android 4.3) on his Xperia neo and it actually works great.
