While we await the CDMA version of the Palm Pixi here in the States (Sprint), a GSM version was allegedly spotted in Vietnam. The GSM version has only 4GB of internal storage versus 8GB on the CDMA model. Yikes. The GSM version likely has a ways to go before we see it in production. Hopefully a GSM version will be available in the U.S. at some point (AT&T?), and hopefully it will have more than 4GB of storage.
