Yep, just like Nokia and Samsung phones, you can also send Flash SMS from your iPhone and can play funny pranks on your friends :D For those who don't know, Flash message is the one which is not stored in your phone's inbox but is displayed directly on its screen. Now here is a catch, other cellphones OS including Symbian, Android and Java lets you to view the cell number of sending party but iOS has a bug which keeps sending person anonymous ;)

Steps to Send Anonymous Flash SMS From a Jailbroken iPhone:

  1. Open Cydia on your jailbroken iPhone and add the following repo:

    iPhoneDelivery Repo

  3. Search and install iPhoneDelivery app.
  4. iPhoneDelivery

  5. Once installed, go to Settings -> Messages and set Delivery report to Flash. Also turn Character Count ON.
  6. iPhone (Flash SMS)

  7. Go to Messages app and create a new message. Type your message with an exclamation mark ! in start and send it to any iPhone user you want :P In this case, its my boss :P
  8. Type Flash Message

  9. This is how Flash message will appear on my boss's iPhone :P
  10. Flash Message on iPhone

WARNING: You can send a Flash message of max 160 characters. Sending a message with more than 160 characters will be received as a normal text message :P

      I believe the app was recently updated for iOS 5, although it seems to not work very well with iMessage.

    One of my friends received these flash messages as BAD PRANKS. They send continuous messages throughout the night, and keeps saying bad things like “You’re fat” and etc. It’s really bad. It has been days since she’s been receiving them..

    Any ways to find out who messaged? Or to block them entirely? Please help.

    Is it free to send flash SMS ?

      Pramod9 years, 1 month ago

      Don’t think so. Standard SMS charges do apply for the flash SMS messages as well. Differs from country to country though.

      Totally agree with you !

        Warrior9 years, 4 months ago

        Remember, before you intend to send, be sure you check the settings again in Messages… because I find that the system will revert to its original settings if you have re-spring or turn off your mobile..

    Jker9 years, 4 months ago

    I dont have an option under messages that says flash.
    delivery report:

    inserted in the conversation
    full screen alert
    only the sound

    I dont see where it says flash

    Interesting, you two got it working. When I do it, the message is sent obviously from me. It’s pretty str8 forward, I wonder if it’s fixed in newer iOS versions.

    What are you two using? I have an iPhone 4, running 4.3.3 and testing with another running 4.3.2.
