The HTC One S available from Canada’s Bell seems to be getting itself a quick maintenance upgrade. The build is v1.84.666.9 and it mainly brings fixes for WiFi performance and improves the MediaLink experience. It also fixes rare occurrences of the device suddenly power-cycling. Those with the hardware should be able to find the upgrade in the About Phone > System Software Updates menu under settings. Be sure to see if you can pull it down. [via MobileSyrup]
