We know that AT&T is going to offer two webOS models from Palm by the first half of this year. It is obvious to expect the two to be GSM versions of the Palm Pre Plus and Palm Pixi Plus. And now we have a European testing and certification company, TUV Rheinland, that appears to be testing two models-the P101UNA and P121UNA. We have already cracked the code in the past with the P101 representing the Pre Plus and the P121 standing for the Pixi Plus. The UNA represents the GSM version of the phones. Thanks to the lab, both devices now have their US + Canadian NRTL Certificate which means that the GSM models meet OSHA and SCC (Standards Council of Canada) requirements. No, it is not the FCC so there still are some other "t's" that have to be crossed and "i's" to be dotted before we can feel comfortable with saying that the webOS duo are coming to AT&T. But knowing that GSM versions of the Pre Plus and Pixi Plus are out there is a necessary first step in the journey to the carrier and Luke Wilson.
