Well, Corsair, how does Janes know the H4 is air-to-air? If it is indeed an a2a missile, then its GREAT news! But you have to take everthing with a bit of salt... not be overly optimistic. And Janes has gotten info on the JF-17 wrong on many occasions in the past... so I don't trust what they say. besides, if Pakistan is making a weapon, I'm sure our media has more accurate info than them.
and gf0012 to answer your question basically:
Right now, no pakistan F-7 has any BVR capability.
