Ok guys, I have an iphone 6 and updated it to the latest version a few days ago. Since then I am experiencing similar issues.
When I turn the wifi off, I am able to access any Safari hyperlinks by doing the following:
Settings --> Safari --> Open Links --> and i selected "In Background".
However, the phone still freezes when I am trying to open a hyperlink from my mails and from any other applications.
When I turn the wifi on, it freezes Safari even with the above change. Then, tried to turn off JavaScript (and in combination with the above setting), Safari hyperlinks work. Still the phone freezes when clicking on hyperlinks in any other apps.
Hope this helps.
I'll get back to you if I find any other solutions (but hopefully, we will receive a software update soon!) 🙂
