附上更新內容說明
1. email notification improvements
previously, if you turned on email notifications using the facebook.com website, then logged out and logged back into facebook on your blackberry smartphone, your email notification settings would be turned off.Now, with facebook for blackberry smartphones 1.9.0.28, email notifications are left enabled if you change email notification settings using facebook.com, then log out and log back in to facebook on your blackberry smartphone.
2. Background polling
previously, if you set the background polling option to never, then logged out and logged back into facebook for blackberry smartphones, the polling setting would be set to 10 minutes instead of never. This issue has been corrected so the background polling option will remain at the never setting.
3. Photo upload freeze fix
in the past, users may have seen their blackberry smartphone freeze when sending a photo to facebook from the media folder on their blackberry smartphone. This issue has been corrected by this maintenance release so no further freezing should occur
