The boys over at Engadget Mobile managed to get their hands on what appears to be a slide deck showcasing just about every smartphone headed to AT&T this year. Some of the slides may be a bit off as far as launch dates are concerned but wow, what a lineup AT&T has in store for its customers. We have a few obligatory Windows Mobile devices — the HTC Fortress (Touch Pro2), HTC Warhawk (Touch Diamond2) and the HP iPAQ K3 which will run Windows Mobile 6.5. The expected BlackBerry offerings will include the Onyx, the Magnum, the Gemini and the non-flip Pearl 3G. AT&T is also expected to get the rumored Palm EOS in the latter half of the year and last but not least is the HTC Lancaster, an Android-powered QWERTY slider that steals its styling from the Touch Pro2 and makes the G1 look like a kid’s toy. Hit the jump for the individual slides with all the juicy details.
