I posed this question to Connect4U and here is there response:
Both got different replies is due to the reason of timing. Initially the information we gotten are based on the earlier batch which Imos decided to improvised, hence the long delay. The second answer was given based on the test unit (revised version) sent to us. The new design comes with 2 different types of adhesive too. First one on the top and bottom part which is colored and the second one is the normal adhesive on the middle part which is transparent.
We understand there's concern that the sides might attract dust. Kindly take note that the new version do not have adhesive on the curved edges, hence dust are not going to stick on it. And secondly, the curved is a glass (Corning glass to be exact). We knows rubber/plastic attracts dust, hence some brands have such issues.
Hope this sort out the issues.
