How to delete all entrie to phone book (Phone Memory) ?
With the Menu Phone Book is not work.
I can't access to the number recorded in the phone Msg : Invalid selection.
But when i see Memory status there are 41% used memory in phone.

Thanx

You have to change the current memory in use from "Sim Card" to Phone"! It's in options in your phone book menu!;)
