Could Itunes version 11 affect internet tethering on an iphone 4S?

I have a Macbook and i was able to tether my internet Connection just fine With an older version of iTunes. But I thought it would be better to have the newest version of iTunes.
So I downloaded the newest version of iTunes, and as soon as I opened it My tethering has stopped working and has not worked since.
Anyone else have this problem?

Best thing to do to test that situation would be to revert back to the old version of ITunes. There are always bugs that come up in software update which leads to more updates. I personally have not heard of this problem so far but everyone I know has an IPhone 5. Like I said go back to the old version of Itunes and see if it still happens. That way you know if it really was ITunes or not.

  • Will replacing my existing laptop hard drive affect my iTunes/iPhone? I'm pretty sure I already know the answer but with me possibly losing my data from the main 2 devices I use in life I want to be sure. I've made a system image using windows 7's built-in backup software and will be replacing my faulty hard drive with a larger capacity new one. Seeing as it's a full system image it should save all the iTunes program data, settings, media (songs/videos) and iPhone backup shouldn't it?

  • Why is USB internet tethering not working on my office PCs? I tried to access internet on my office PCs by USB tethering with my Iphone and Andriod phone but it was not working. USB tethering was successfully working on my home PCs and all my friends' PCs but not on my office PCs. What settings on my office PCs do I have to modify? I believe that issue is not related to windows OS versions because all the PCs are using the same OS.
  • IPhone internet tethering Optus? On your iPhone you are able to share your data with your laptop or other devices (tethering). Basically you can use your iPhone as a 3G modem. I'm on a prepaid Optus plan that includes 5GB of data BUT Optus decides that they think we should pay $15/month to use this iPhone feature with separate data. Is there a way I can do this for free without Jailbreaking my iPhone?
