Help Sending Pic mail to Non iPhones

[Pollabr]

Hello,

I have an iPhone 4 with the latest iOS and its not jailbroken. I use iMessage, and just found out that I can send picture mail to another iPhone fine using iMessage but I cannot send pictures to other smartphones when iMessage is on. I have to turn off iMessage and use mms to send picture mail to other smartphones. Is there any way to correct this?
