So now that the second raft of Sony Xperia devices are finally receiving the long awaited Android 4.3 update, I’m sure that there are plenty of folks eagerly glancing at the notification area and Sony PC Companion in anticipation of that firmware update notification. Some of you may also be constantly refreshing your device’s XDA forum page, meticulously keeping track of every relevant tidbit of information. If this sounds just like you, you may want to check out XDA Senior Member Macmol‘s Xperia Update Checker.
A tool for PCs, Xperia Update Checker enables you to check the current firmware of your Sony Xperia device. Besides the initial categorization of individual devices, firmware information is also organized by the region, branding, and customization number of your device, such as “Netherlands; Vodafone; 1266-1618.” Xperia Update Checker also allows you to check for links of firmwares for a particular device that you can download. It should be noted, however, that this tool only supports Xperia devices with Sony branding (e.g. Sony Xperia V) and not the Sony Ericsson branding (e.g. Sony Ericsson Xperia Arc), and not all Sony Xperia devices are supported as of yet.
So if your finger’s getting a bit tired of constantly clicking refresh on your browser and Sony PC Companion, check out Xperia Update Checker over in its original thread for more information._________
