Treo 750v, which featured Palm's WinMo take on their long-lauded threaded SMS feature, now you too can have IM-like text convos with your pals with a minimum of hacking. Merely install the app, make two quick registry edits and restart your phone. (If you're down with MMS you may have to reconfigure your MMS servers.) It worked like a charm when we tested to see if it was the real deal, though we understand it doesn't work with VGA displays (i.e. the Universal.) We're definitely not vouching for the legality of this one, however.
