I went and chatted up Palm Support. They were really nice and (apparently) fixed the problem. I'm now running my new Pre3 on my old account (contacts, apps, and all). I tried to ask the Palm folks what they did to "fix" my profile, but that online messaging system is so jacked up it kept connecting and disconnecting while they were telling me which procedures to follow. Really annoying.
Thanks to everyone for walking me through this little episode. I swear I'll stop spamming this thread.
One more question, though. As my Pre3 is loading up all the stuff from my profile, I've noticed that many of the patches that were on my old Pre+, and were unavailable when I loaded up Preware on the new Pre3 (while using the extra profile), are now loaded and active on the new Pre3 (now running the old profile). Put simply, the Pre3 has restored several patches that I had thought were unavailable to me now that I'm running a Pre3. Am I going to have other weirdness in the future?
ex. of patches include: colored percentage instead of battery indicator icon, close phone app on 'End Call', clear quick launcher bar, and others, I'm sure. Patches that are not currently active are the 4x4 app menu patch. I'm worried about patches that I searched for and couldn't find when I was running the Pre3 on a new profile and now have from my old profile restore.
