Weaker signal on 4s after 5.01?

When I first got my 4s it worked mediocre at work where there's a deadzone. But since the 5.01 update 3G doesn't work at all. Bundle this with the fact that I can no longer switch manually to edge and I now have a phone that is totally useless while I'm at work.

Anyone else noticing a weaker signal since the update?

I think the inability to switch back to EDGE manually ought to be fixed. The issue I have is that AT&T's network by me gets overloaded during the day. Thus, while it displays 3G and can accept voice calls, data often gets bogged down or even stops, despite a moderately strong signal.

That said, I think there are some other bugs in 5.0.1 that occasionally result in the "No Signal" error.
