Just loaded 23540 rom w/ htc messaging on verizon. First off, everything is running generally well as usual. Dibbs, thanks for including the clear type landscape fix.
ivwonka, I am syncing to exchange with about 100 contacts, over 100 emails in a few folders, 22 tasks, and just over 100 calendar items. So far everything is working good. However, I don't have to type in any unlock code.
Regarding some posts about the EV/1X/ActiveSync icon on the taskbar, if you run the Verizon provisioning it does break that icon, and it gets stuck on Active Sync icon. If you do not run the Verizon provisioning cab then the icon works, and the only issue I found was the keyboard mappings, which you can fix with rhodium keyboard driver and/or the "verizon keyboard fix.cab".
