Data Network Wonky after 4.2.1

Well, before I'd go off saying that iOS 4.2.1 was the culprit, I would do more testing to differentiate between the two.
I haven't had any problems with my connection before or after the update.
I don't remember seeing anything get updated after 4.2.1, but how would I tell?
If I look under settings I see: "Carrier AT&T 9.0"
This morning I noticed that my 'Data Roaming' setting was turned off. I don't remember doing that. I'm wondering if the 4.2 update did that.
Check yours. Is it on or off?

Yeah, now that I think about it, what the heck would you roam TO in the U.S.? AT&T 3G is the only 3G the iPhone can use so it's not like roaming is actually helping me anywhere I go.
Oh well, just a though.
There is one website I use for work and I always this message. I hit refresh on the browser and it loads up normal.
I'm in the UK so i can't see what the differences are but i do remember reading somewhere that AT&T also got a carrier update shipped with the new update. You say you've reset network settings. Perhaps you should do it once more or its time to reset all settings
I upgraded my 3GS, and I am having the same issues. I'm on AT&T. I'm thinking it might be the update, but not sure.
Update: I just reset my Network settings, and so far that seems to have fixed the problem. Will monitor to see if signal remains stable.
Update: Sorry, spoke too soon. Still having issue. If anyone has any solutions, it would be greatly appreciated.
When you upgraded to the new firmware did you use the "Update" or the "restore" button? Also once you had installed the firmware 4.2.1 did you sync from backup or setup as new phone. If you Upgraded , or used sync from backup that is most likely the problem.
Do another update, but this time use the restore button, and then to be extra safe set up as new phone.

I gave ATT technical support a call. We ended up doing the following:
Settings->General->Reset->Reset All Settings
While all my settings got zorched, it does appear to have fixed my problem. Perhaps this had a similar outcome as the steps chakraj was suggesting.

Does the "Restore" or "Set Up As New Phone" erase all info in apps? I would guess "Restore" does.
I think the issue might be AT&T. Currently not having issues right now. But, we will see.

I can report exactly the same issues with network connectivity. In actual fact this started when I was trying out 4.2 GM and I went back and forth to and from it for several days. Simply put, I seemed to have had continual intermittent 3G connectivity issues which, on reverting to 4.1 disappeared. 4.2.1 GM was exactly the same (and thus the 4.2.1 release version). I have gone back to 4.1 and hopefully there will be a fix for this. And yes, I have gone through the cycle of resetting all settings etc.
