Can't log into web sites on iPhone 4s.
I recently upgraded from an iPhone 3Gs to an iPhone 4s running iOS 5.0.1. I've recently noticed that on the iPhone, I can't log onto any web site that requires my ID and password. Basically the information is not recognized by the web site. I had no problem logging onto these same sites on the old 3Gs. I've checked that the IDs and passwords are being entered correctly.
If I use my iPad of my MacBook Pro, I can log onto theses same web sites without a problem. I've tried resetting the iPhone but that has not fixed the problem.
The log in problem only happens on the iPhone.
Web sites that don't require an ID and password seem to be working fine on the iPhone.
Has anyone else run across this issue? Any ideas how to correct it?
