Yes, it's happening quite often when browsing on the phone here. Doesn't seem to matter which browser I'm using either; although, I primarily use IE. Also running the stock ROM and have noted it occuring on all available radios - running Telus 1.04.05 as it's turned out the best performance in my area. It only occurs on the data connection - I don't see the issue with WLAN or ActiveSync and it doesn't seem to affect tethering.

The workaround I use is to set the Phone Off button press-and-hold to turn off the data connection and use it when it occurs, then I'll hit refresh and it will reconnect and work for a bit until it happens again.

It's very annoying and I believe it has to do with the fact that the IP/DNS settings for the Sprint data connection cannot be set manually - they always reset back to automatic. I haven't dug into the registry yet to see if it can be fixed by a hack as I suspect, but may look into it soon as I've lately been using the browser over data more often.
