I'm about to sign a new contract with our telco and as part of the package we can get a free phone. I already have a Galaxy GT I-9000, which I am happy with and my wife needs a new phone. I'm tossing up between the Samsung GALAXY S III mini and the Samsung GALAXY Ace 3. From the specs I can't see much difference. One is 4G capable, the other 3G extended. (We don't have a 4G plan.) It seems that the Ace has a TFT screen, the other an AMOLED.

Does anybody know of any worthwhile differences?
