I'm still not sure what the real-world implications are given the frequencies available to either the i- or a-versions, and so I'm still in limbo about which version to experiment with. Or is it even worth trying, no matter how badly I want this phone?
If you want an Xperia ray, the "i" will give you the best experience for 3G with T-Mobile. Obviously you must take into consideration your roaming situation, but otherwise, the "i" is for you.
