I wasn't experiencing spontaneous reboots, but with dolphin browser installed I was experiencing some serious glitches with widgets. After having it for several days, I couldn't even open the default browser or the dolphin browser. Uninstalled and everything works as it should now.

 

Dolphin Browser is terribly designed anyway. The only thing I liked about it is gestures. If they implement that into the default browser, there won't even be a need for Dolphin on the Market anymore.

 

The only issue I've had with Dolphin is that since it started using the SD card for storage, if I mount the sd card to transfer stuff from my pc it causes Dolphin to FC.

Otherwise it works great.

I do admit that the pinch-zoom is kludgy. I do wish the double tap had been left in. But mostly I don't need to zoom, so it's ok.
