Possibilities for transferring image with text

I went thru StackOverflow for finding out different solutions for sending/fetching images along with text via 开发者_开发知识库iPhone apps. There are few options like:

1-Sending content via Email to other email address(Just like iphone app,POSTAGE do)

2-Sending/Receiving in-app SMS but that is only supported in iOS4

3-Use some intermediate Server to send/receive Data.

I was more inclined towards option #2 but did not find ways to accomplish it. Option #3 would be depending on 3rd layer which could go down. I have not found a way to read iPhone's inBox or connecting directly with IMAP server

What would you recommend?I am desperately looking for solution.

You can email images as an attachment using the MFMailComposeViewController class.
