I've used the following on 48:
Vodafone Smart/Huawei U8160
Vodafone Smart III 975/Alcatel V975
Huawei G300/U8815 (which I'm currently on)
Haier W910 (which I'm trying to move over to - but not finding the time yet!)
I've tried the mini version of S4 I think, as that's the phone I think my friend has from the Galaxy ones... quite nice, I have to say. If I could have the iOS system inside the S4 mini, that would be great.
