Samsung has silently updated the Galaxy Mini with a new processor. The original model had a processor running at 600MHz, while this new S5570i model is clocked at 832MHz. An updated Android version is also pre-installed on this.
Here in Finland the name didn’t change with this update. It is still called the Samsung Galaxy Mini. In some other parts of the world the name has changed from Galaxy Pop to Galaxy Pop Plus.
Hit View Post to see living proof of this already being available in Finland ;)
