I upgraded at about 10:30AM PST it's now 10:45PM PST and it's still working.
side note:
I called apple three days ago and escalated the call as he the rep basically kept offering me an out of warranty repair -- which I declined. the second guy on the phone said "I've had a lot of people call in about this but we made millions of iPhone 4S' so some are bound to have issues" which is quite frankly a terrible thing to say when dealing with a customer. I told him about a bunch of threads here, this one and another (it had 500k views), that I cant find at the moment. He basically shrugged it off. he did tell me to go to an Apple store, so I went in the next day.. first person I spoke with again told me "I've seen this issue a lot." He plugged it into their diagnostic tool and he found no issue. he then did a hardware restore which is apparently different than an iTunes restore but it didn't fix anything, then he reset the network settings which I've done probably 1000 times since the iOS6 upgrade and it either works right away for a few hours or my wifi remains grayed out for 2-3 hours before allowing me to turn it on again... this time it worked right away. he said "I've fixed it now, but it may be a temporary fix so come back when it happens again". I went home, where it worked exactly 4 hours then crapped out again. So I went back to the store a second time. The next "genius" did the exact same troubleshooting as the first but this time the WiFi remained grayed out so he told me I'd have to do an out of warranty repair for $199(CAD), I told him that's not acceptable as there are thousands of customers experiencing the same issue.. and that I've already gone through faulty Apple products that were later replaced a few years later (I bought 3 1st gen iPod Nano's that were all replaced by apple after they found a fault with the batteries). sooo he told me, I could escalate to an engineer, if they find that there is a manufacturing fault they will replace the phone for me at no cost. I'm going to leave it for now as it seems 6.1.3 fixed the issue but I'll be sure to go back to the Apple Store if the issue arises again.
*edit*
Apple "genius" said it may take a week to hear back from them about the engineers escalation.
