Sony Ericsson is a long-lasting mobile phone producer. For a long time, their mobile phone design was somehow dull. Feedback received from their customers changed the idea of how a mobile phone should look from the developers' point of view starting with the Aino model.
You can see some of the repetitiveness in Aino's design still. The first part above the screen (where "Sony Ericsson" is written) is so much similar to other Sony Ericsson mobile phones like K750i, K800i, K810i, with minor modifications.
