While BlackBerry users prefer to communicate via BBM, we’re still stuck with regular old text messaging when communicating with non-BlackBerry users. The thing with SMS is that it’s fickle. Your device automatically deletes SMS by default. You can change this by going to Messages – Options – Message Display and Actions and changing Days To Keep Messages to Forever. But that can cause storage issues, especially in older BlackBerry models. If you’d rather your device continue wiping messages but still retain a backup, the Txt2mbox app can come in quite handy. The biggest catch with the app is that it requires a webmail address with IMAP. Gmail fits this bill perfectly. At very worst, you can create a dummy Gmail account that just stores your SMS backups. (Just like you can use a dummy Gmail account to filter spam.) The app automatically syncs with your IMAP account, storing all of your text messages, both sent and received. Even better, it stores sent messages in your sent folder and received messages in your main inbox. With growing on-board storage for BlackBerry devices, you can reasonably store messages indefinitely. Older models, with as little as 64MB of internal storage, absolutely require frequent cleaning. But even with newer devices, it can pay to keep deleting old messages. After all, when it comes to email you still have the option of searching on the server. With text messages, however, that’s not an option. An app such as Text2mbox helps you keep those backed up, no matter how you choose to store messages on your BlackBerry. You can get Txt2mbox at App World for $2.99. Even better, you can get a free trial to see if you like it. Hat tip BerryReview.
