last night my wife and i put v.1.0.12 on our respective BBs. she has an alltel curve 8330 and i have a verizon tour 9630. syncing would not work either way, although we were both receiving the honeydew messages in our PIN messages folders. when trying to do a manual sync on the 8330, hers was throwing some sort of java error (i don't know specifically which, b/c we've since uninstalled the apps in hopes a reinstall might fix issues).
based on other posts, i ensured that permissions on both phones were set to allow all. i also made sure to download the 4.7 build for my tour and the 4.2+ build for her curve.
