So yesterday I received a notification for a software update on my Sprint Hero. So I of course downloaded it and Voila! A lot of the buggy issues I was having after installing 2.1 are gone. Seems they fixed the update. Software #: 2.27.651.5 I no longer have a huge lag when making calls and the phone is not restarting after getting on the net along with all of the other issues there were. So I am pretty stoked right now.
