After looking at my inbox I realized a couple things. One that I need some serious help for my addiction with GetGlue and two that I need a quick way to delete all the messages that piled up in my inbox. Fortunately for me, our BlackBerry devices come with just such a feature. That way we won't be sitting there manually deleting each one. Just follow these steps and you'll be on your way.
Delete a range of messages - devices with keyboards
All you need to do is go into the messages folder from the home screen. Using your trackpad/trackball highlight the first message you want to delete. While pressing and holding the CAPS/Shift key (left or right) slide your trackball/trackpad up or down to select additional messages. When all the ones you want to delete are highlighted, take your finger off the CAPS/Shift key, press the Menu button and click on Delete Messages.
If you don't want to repeat the deletion process on your work or home computer make sure you choose the delete messages on mailbox and handheld option. This will make sure your emails are removed from both places so no need to worry.
Delete all messages prior to a specific date
Another way to delete a whole bunch of messages is using the delete prior option. Simply place your cursor on the date line, press the menu key, and select Delete Prior. All messages prior to and including that date are erased. Just to warn you this includes BBM, SMS/MMS, emails from other accounts, sent messages or any other message type you chose to populate the messages folder. Please note that emails deleted using this method are only erased on your device. They are not removed from your inbox and you will have to delete them again from your computer.
You can also clear multiple items using the search function while in the messages folder (Mesages -> Menu -> Search, or tap on the search icon at the bottom). After entering your criteria you can delete any or all of the items in the search results window by following the same procedures outlined above.
If you own a Torch or Storm I learned this trick in the forums. Take one finger and tap on the first email and then use another finger to select the last one at the same time. You are basically touching two messages at once. All messages in-between your two selections will be highlighted. If you want to include additional messages simply slide one of your fingers up or down. Then you can press the Menu key and click Delete Messages or tap on the delete icon at the bottom to wipe them all out. Torch users can also use the small menu popup that appears after selection to delete.
There you have it a great way to clear out your inbox and prevent it from overflowing with unwanted messages. Just make sure you don't let your emails get as out of control as mine.
