Downloaded iPhoneDelivery from Cydia and my setting is Delivery Report : Flash and Delivery Mark : Discreet. And they worked fine when I downloaded it last night. Was able to send Flash messages using the default Messages app by attaching a ! infront of the text. And it was fun. I sent close to 10 texts. And when I tried to try again an hour ago, my friend said they received it as a normal text. So I rebooted and tried again but its the same thing. Any help guys? Reinstalling iphonedelivery and rebooting didnt help. And by the way, the FlashSMS app isnt supported in my country yet
