Apple (AAPL) roundup: 1) The Verge gives the new iMac a review score of 9.0 out of 10, and praises its display, ultra-thin design, and performance. The speakers are criticized a little. 2) Apple is refusing to let the iPhone 5 run on the 4G LTE networks of carrier partners until it tests a network's performance. That might be slowing down the phone's international rollout pace. 3) Apple is reportedly looking for a third iPad Mini panel supplier due to AU Optronics' (AUO) low yields, which are believed to be hurting supplies.
