Apple has released the next version of iOS 6 which is 6.1.4 and is only released for the iPhone 5. The new release has just given an update that brings an updated audio profile for the speakerphone.
Meanwhile tinyumbrella was also updated so that you can save the shsh blobs for your updated iPhone 5. Although it is of no use at this stage for saving the shsh blobs, but it can be helpful if we upgrade later and we need to degrade iPhone 5 to this version i.e if there is ios 6.1.4 jailbreak available and you upgrade to next ios 6 or ios 7 then you can use these blobs. So I have given below the download links for tinyumbrella as well which you can use to save iphone 5 shsh blobs after you upgrade your iphone to ios 6.1.4.
Below are the download links for iOS 6.1.4
Download Links for iOS 6.1.4
You can upgrade by downloading the above files or using on the air OTA option in the settings of your iphone 5, we recommend to not upgrade because there is no real difference in ios 6.1.3 and 6.1.4.
