If you want to check for new emails from anywhere on your iOS 9 iPhone then install new jailbreak tweak, called Postman. Usually whenever you want to see if you have received any new emails, you need to launch the stock Mail app on your iPhone and pull down to refresh the email inbox of your choice. It is not convenient especially when you are working in another app.
With Postman tweak installed you can manually check for new mail in the stock Mail app using Activator without leaving what you are currently doing. So using the steps below install Postman tweak to view for new emails manually from anywhere in iOS 9.
How To Check For New Emails From Anywhere In iOS 9Step 1. Use Pangu tool for iOS 9-9.0.2 devices to jailbreak your iPhone. If you are jailbroken skip this step and move to the next.
Step 2. Now navigate to Cydia and search for Postman tweak. Download and then install the app on your jailbroken device.
Step 3. Once installed, you need to assign Postman an Activator action of your choice. You can do it from the Activator preferences pane in the Settings app or from the Activator app on your iOS 9 Home screen. After that you can use the gesture at any time to invoke Postman’s functionality.
For example, you can assign Postman an Activator action of double-clicking the Status Bar as shown on the picture below. So the next time when you will double click your status bar, no matter where in iOS you might be, iOS will fetch any new emails for any of the email addresses you’ve configured in the mail app.
For Postman to work best you need to disable all automatic checking for new emails for inboxes on your iPhone and enable notifications for the Mail app, such as banners and icon badges.
Postman is a useful jailbreak tweak for jailbreakers that allows them to quickly check for new emails from anywhere on iOS 9 iPhone.
