I am able to send silent sms for 2nd edition as well as for 3rd edition. I want to know, when a sms is going from the handset an icon is showing at the top(outbox icon) till the sms is send, so can we stop that icon. And if the SIM is a prepaid SIM one flash sms comes after sending the sms telling about the current balance. Can we block this flash sms also? Waiting for your reply. I have tested for 2nd edition and 3rd edition Nokia handset.
