The Eris was only rooted "reliably" about two weeks ago. Previously, right around the same time VZW/HTC was testing 2.1, a leak method was released (by HTC ??) but if you had already updated to the "beta" version, you were S.O.L. until two weeks ago. I realize activity with the Eris may have increased a lot in those two weeks, but it was very popular before (based on postings).
