Questions about 4e Gear Options

[Omar]

Finally finished with the crunchy part of my character, now I am getting into gear.. and questions are coming up. Help?

Commlinks:
- Response is how quick it processes, I get that, and System is tied to it (cant be higher than response). You cant run programs higher than the System rating. Other that this, do I have to pay attention to these numbers for any reason?

- How would I go about preventing someone from hacking my commlink.. say.. with Black IC? I was told it was possible, I am just having a hard time figuring out how

- If I connect with my Commlink via datajack, do I need AR Gloves, or subvocal mic, or any of the other add-ons? Wouldnt a plugged in Commlink with a Datajack and Cybereyes allow for automatic visualization and ineraction (when you wish to, via mental impulse) with AR?


IDs:
- A Liscense will allow you to 'legally' have any item thats restricted. They then have to be tied to a SIN, which is also probably fake. Is it really worth the hassle of getting a separate lisense for every piece of restricted gear, just to have it all linked to a SIN which could fairly easily be erased or compromised?

- How many and what rating of Fake SINs are 'typical'? I figured 1 for legal things (rent, bills, etc), and 2-3 for less than legal things... but the ratings is what I cant figure out.


Cyberware:
- I cant seem to find a piece of tech that was in previous editions, and am not sure if its necessary or not. Used to be you had a piece of cyber that would let you think of what to say, and you would 'say' it via a phone your plugged into or such. Kept you from having to have subdermal mic or speakers. I think it was a Mental Link or something?


Thats it for now, but I am still reading...
