I have before I would drop 3g while surfing and have to reload pages etc. I did the update lastnight and have been surfing for about an hour without any problems. I'm very happy.
Browser is alittle slow here but not nearly as bad as some are making it out to be. I'm curious why it so drastically differs since everyone with 2.01 should be suffering.
update: just did another speed test, wayyyy better, pages are loading with no problems and scrolling is all good. deleted dolphin, and went back to stock browser. i dont think dolphin is ready yet. still needs more work on pinch and zoom. love dolphin,but its just not ready yet.
