Help 30KB picture msg, has been "downloading" for two days

[bottlerocket]

So someone sent me a picture msg from their iPhone and it's stuck downloading...for like two days now. Shut off phone several times, removed battery...still just says "Downloading" in gray. When I click on it it just gives me the message details: Type: multimedia msg, etc. I was using 3G only when I first opened it, but I've tried wi-fi as well. Any ideas? Thanks.
