SR4 Gear Clarifications Options

[Mantis]

This only applies to SR4. I want to ask if there has ever been any consensus on a few bits of gear.

First up is the CMT Clip commlink. Is this a typo and it was supposed to be MCT Clip? This would make sense since MCT is supposed to be a computer company yet they make no brand name commlinks. I've never heard of a company called CMT.

Second is the plethora of collapsible pistols in Arsenal. We have a stat block for something called the Collapsible Heavy Pistol but no fluff for it (pg 23 Aresenal). We also have a stat block for something called the WW Infiltrator in the compiled table on pg 175 of Arsenal but again no fluff. This weapon is different from the Collapsible Heavy Pistol as well.
So was there ever any fluff for these guns? Were they statted and then the fluff removed? If so any idea why?

Third and last, was there ever any errata on the emotitoys? That is why does the toy cost so much less than the software it comes with? Never mind the cheese factor of the thing. I've got a house rule that works (basically it acts as a teamwork test so if you suck at the skill it isn't going to help you that much).
