I am interested in the following question:

Is it known that $2$ is a primitive root modulo $p$ for infinitely many primes $p$?

there is some information about Artin's conjecture in http://en.wikipedia.org/wiki/Artin%27s_conjecture_on_primitive_roots

I need to know if it is up to date and if one can say something about the case $n=2$.
