What did you get in the end? I recommend you just to go to a shop and get a feel of the phones.
I'm also looking for a small phone that I can use with just the thumb... don't want moblets. Still deciding between the Sony Xperia Go (looks ok, feels a bit cheap but good specs) and HTC Desire C (looks good, feels good but worse specs). I was thinking on waiting on a possible mid-range WP8 that might have this form factor since top-tiers are dedicated to big ass phones.
