"I was hoping this would allow me to ssh into my phone to make/take calls and send/receive texts. Does anyone knows if that's possible?"

I send SMS from the command line by curl'ing twilio ...

  curl -X POST -d "Body=Hi" -d "From=3032221111" -d "To=4151112222" "https://api.twilio.com/2010-04-01/Accounts/${account_sid}/Messages" -u "${account_sid}:${auth_token}"

I do at least half of my testing this way, from inside my terminal that I am already working in (I wrote a little sms script in /bin/sh).

Of course this means that your phone number has to be at twilio (either source the number from them or port it to them).
