What people are complaining about is the inability to enter a NEW PHONE NUMBER to call. Not from contacts, not from facetime or webpages, which is what shows up in spotlight.
I get so sick and tired of people posting crap for solutions that aren't valid, don't work, and they never tried, they just copied and pasted, THINKING it should work.
When I see a screen shot of your famous "ala calculator function" dialing a "phone number", wait never mind. You can't do that...
What? Are you for real?? cmd-space type in phone number (or in my example 2+2) and it comes up and dials the number (or in my example the result) which you probably can't do the maths.... is 4.
I get so sick of morons commenting when they haven't read posts properly.
