I've spent the last couple of hours looking here, and I sort of see some answers but nothing definitive. My DX is currently on 2.3.15.MB810.Verizon.en.US . The phone tells me it wants to update to 2.3.340, so I try that. It fails every time. I am not really sure I want to try an SBF. I am rooted using Z4. Not much beyond that. The only reason I rooted was to run the WAP and SeePU. Advice?
