As someone who's almost a day-one Pre user, I can attest to Cantaffordit's recommendation...get Preware! Look for the Preware Documentation app in the app catalog. It's MORE than worth the 99 cents.
I'm in the same boat. I also bought an ATT one the other day. I see a lot of good things being said, but I also see a lot of confusing info...
-doctor it to a UK Pre3, don't doctor;
-paid apps, no paid apps;
-no OTA updates, OTA updates...
Best I can tell (and PLEASE someone correct me if I'm wrong!), it should be activated normally (SIM card, Palm Profile) for full access to the app catalog (i.e. paid apps) if you, your Pre, and your card are all US (or whatever country). There are OTA updates (if that matters any more), but no webOS Doctor (and S/N shows up as invalid on HP site). Is all that right?
Question... If webOS gets messed up on it, is the Euro webOS doctor a potential solution?
This is gonna be an adventure!
