That was not my experience at all actually. I started this thread because I experienced a g-mail push issue much worse and very different than described above.
First, my problem started PRIOR to 2.01. And the problem isn't/wasn't that gmail push began to take 2 minutes, it was a change from instant to HOURS. While instant is obviously better than taking 2 minutes for push, that difference makes no real world difference to me personally.
In any case, my gmail push on the Droid originally worked just fine, then 1 day about a week prior to 2.01 started to take hours. The issue did not change at all with 2.01. Then it was just fixed as of a few days ago, and is working fine again, with no hint of why the issue started or stopped.
I am happy my push gmail is working again, for sure. But the issue described in the link above is separate from my issue completely, and not my experience at all ..
