I have seen so many folks complaining about problems after the DL09 update. I have not had any of these post update problems. My SD card still mounts fine, just like it always did. There is no VZW popup when I mount it. I do not have the double caps with Swype and it seems smoother after the update. Battery life is just as good as it was. The phone seems much snappier and the GPS is fantastically quick now.
Phone is stock, I use LPP, Widget Locker, Bedside, Locale, Custom Car Home, Office Suite, k-9 mail, Jorte, GTasks, and Checkmark among others. I have had absolutely no problems so far at all with the DL09. The only thing l lack is the dock speaker jacks working and being able to record from Tune-In radio. Other than than that, I don't know what else I could possibly want. Why should VZW issue a fix for what isn't broken? Most likely there is interference with some other app you guys are using and that can be murder to trace down.
