One of the bugs being repaired by the update, is one that fails to encrypt email attachments. Apple originally failed to admit that these attachments were not being protected. A German security expert had spotted this flaw as far back as iOS 7.0.4, and had alerted Apple to the problem. After iOS 7.1.1 was released in April, Apple admitted that it had a problem and said it would soon issue an update to fix it.
Besides repairing the encryption problem, iOS 7.1.2 is also supposed to fix a problem where the email app doesn't download email messages. Another fix is supposedly designed to prevent access to a limited number of apps via a lock screen vulnerability. Another small fix will handle data transfers from third party accessories.
One problem that has been driving former iDevice users batty, involves iMessage. As we told you before, when an iOS device user switches to a new platform without disconnecting his number from Apple's system, iMessage will intercept text messages sent to the former iOS user, and will not forward them to his new device. Last month, Apple said it would fix this problem.
Sometime over the next two weeks, iOS 7.1.2 should be sent out to your iOS flavored device, so keep an eye open for the notification of the OTA update.
