The same rule of thumb is true with getting every TSB or most recent TSB for your brand new Jeep. In as much as it might fix some really minor problem, it may just create newer and bigger ones.
So for anyone out there who likes updating their smartphone software regularly even though it is problem free, good luck. Because that's the biggest reason smartphones stop pairing with your car's bluetooth. Don't bother complaining to the dealer because the dealer will always tell you it's your phone. Remember, in as much as your car has a lot of computers and electronics, you can't just stick a USB to your car and attach to your notebook computer with WiFi to upgrade software to match your phone.
The problem with refusing to update your smart phone's software is that some updates include security fixes. If you refuse the update, you may leave yourself vulnerable to having the personal data in your phone stolen - or your signal pirated, etc.
Some vulnerabilities are minor or there is no attack in the field (for now) - others are a matter of concern. You can't just put your head in the sand and not update - you need to research the security implications.
The analogy with PCs is telling - there are a lot of unpatched PCs on the internet that have been compromised and are now available as part of "botnets", or have had their data stolen (like bank account into in Quicken). As our phones grow more and more sophisticated, we tend to put more and more sensitive personal information on them, and security risks grow.
What torques me is that (unlike PCs) Apple doesn't provide an easy rollback for their iPhone updates. You can google around though and you'll see how to do it.
My advice is this: Go ahead and accept the software updates from Apple - then make sure to test your phone promptly with all the bluetooth connections you use. If the patch has screwed things up, roll it back then make a note of the release level and don't update until a later patch. When the later patch comes along, hopefully it will have addressed whatever was messed up and you can get current.
Obviously if the patch you are rolling back has a description that explains all the urgent security issues it addresses, you will have to make a tough call between security vs. loss of function.
Not optimal - but that's the state of the industry at the moment.
