Evening,
Well, I'm still with a dead iPhone, after almost 70 minutes with the Apple Geniuses!
The "Geniuses" at my local Apple store couldn't fix the problem, and said that my phone must be broken, and I'm going to have to pay to get it replaced!
Utterly useless and futile!
GKPM, thank you for trying to help me fix this. I did examine my hosts file, but found none of the offending "gs.applee.com" websites that you mentioned.
I am now in e-mail conversation with some US Apple staff, as with the thread Stuker posted above, it's clear that this is not just my iPhone that's got a problem, nor me as an end-user, but something that's gone hideously wrong at Apple's end!
And with that all said, my faith in Apple is rapidly draining.
Pooch
ADDENUDUM: Just booked a second Genius Bar appointment for Sunday afternoon. Am going to show them the thread, and see what they say, as it seems 99% of 3GS owners - jailbroken or not - all over the globe, are experiencing the same problems! And seeing as iOS5 is "bricking" all of them, then having Apple simply telling people to be patient or wait, is not good enough. They're going to have to start replacing people's phones, as I've now been without mine since Thursday evening, and I can't see others being happy if Apple tell them to just wait for a fix!
