Can I use nRF8001 as a beacon to only transmit data which can be received any phone that comes in range of nRF8001

nRF 8001: How to use it in Beacon mode where in no pairing or Bonding is required and it only transmits some information which cn be received by any phone that comes in range of nRF8001

Yes, you can. You could have a look at the broadcast example in the nRF8001 Arduino SDK here.

But while we broadcast the information.. can i save the information in non volatile memory and then disconnect arduino so that it keeps transmitting the information.... without the arduino.

No, the nRF8001 needs the arduino to control it. If you want a single chip beacon implementation you would have to look towards the nRF51 family.
