So, I'm currently using a 16gb Black iPhone 4S under T-Mobile and earlier, I wanted to check if I could update, even though iOS 5.0 is the only version, when I clicked Update in iTunes with my phone connected, it stated that it could not update the carrier settings. What does this mean?
 
First of all, don't bump.

Bumps. Posts that bring a thread to the top of the New Posts list but add no content to the thread (bumps) are not permitted. This applies not only to posts that say "bump" but to those with the intent to bump, e.g. posts saying "anyone?" or the equivalent. See why and how to avoid bumping.

That error is not critical - and you can continue.
 
So, will this affect my ability to update my iPhone in the future?

It has nothing to do with the os. Just means you won't get the carrier update since there isn't one. You can always do upgrades with an AT&T sim in so you dont see that message.

Oh, thanks. Last question, what do the carrier updates even do if I were to switch out the sim and update?

The carrier updates just allow carriers to set options such as enabling tethering, setting the correct APN.

If you were to switch to a supported carrier, you could get some additional features, such as tethering, at a further cost if stipulated by the carrier.
