Apple has reopened iTunes Connect to developers two days early. iTunes Connect is the portal that is used by developers to submit and manage their apps on the App Store.
Apple had scheduled a shutdown of the service from 22 December to 29 December 2011 for the holidays. However, the site came back up on Wednesday, 28 December 2011, instead.
This means that now developers can submit new apps and updates to the existing apps. They can also administer price changes to their apps. Developers can also see how well they did (in terms of downloads and sales of their apps) during the Christmas weekend, when third party firms reported that app downloads increased 125%.
