Skunks,

I have two 'stupid' questions.

1.0 When you want to know whether a host on network is up or down you ping it,right?Is there an equivalent on mobile phones?If I want to know whether 0725****** is an operational 
      number,is there a way of finding out without calling the number or calling Safaricom to ask them about it?

2.0 We know the location of a mobile device can be discovered using GPS or Cellular tower triangulation.If,for example,a person is using a feature phone then GPS is out of 
      question.Is there a way to tap(for lack of a better word) into the service provider's triangulation info and send the info to the mobile number or store it for other uses?Think of it as 
      a primitive navigation system.

Anyone even with remote knowledge of how these two work will be of great help to me right now!
