I just did my homework, and, it most likely is a typo. Let me tell you why. Both GSM and CDMA devices use Qualcomm MSM chipsets, BUT, GSM devices use the MSMX2XX chips while CDMA devices use the MSMX6XX chips. Here are some examples:
MSM7227- HTC Aria, palm pixi plus (GSM) MSM7627- Motorola DEVOUR, palm pixi plus (CDMA)
MSM7230- T-Mobile G2, HP Veer MSM7630- HTC EVO Shift 4G, HTC Merge
MSM8255- T-Mobile myTouch 4G, HTC Inspire 4G MSM8655- Thunderbolt by HTC, LG Revolution
MSM8260- HTC Sensation MSM8660- HTC EVO 3D
And then there are some pretty unique chips that Qualcomm announced alongside HP.
They announced the HP Pre3 as having the MSM8x55. Notice how they announced it with an "x" instead of either a "2" or a "6". That's because the HP Pre3 will be both GSM and CDMA, so it will be both MSM8255 and MSM8655.
And then there's the APQ8060 chip that's in the HP TouchPad.
