Can anyone out there tell me if there is a pda phone or smartphone available with the following features: GPS, Word, plug-in full-size or near full-size fold-up QWERTY keyboard, email, web browser. Or can you tell me who would know? I've spent too many hours already and haven't found any.

Kyocera 7135 SmartPhone

It has assisted GPS, but that is not accessible to the user as far as I know. It's only available to your cellular provider and emergency services (in case you dial 911). A GPS module and software and be added to it for full functionality.

For Word, add QuickOffice Premier or DocsToGo to it.

For keyboard, add the full-size QWERTY, foldable Stowaway keyboard to it. I have one, and it's very nice.

For Email, it has a free version of Eudora built in. I prefer and use SnapperMail.

For web browsers, it has three built in - WAP, text only, and a full graphical one.
