Welcome to the forums.
How are you forwarding this? Are you in the list of MMS/SMS messages, pressing the menu key and selecting forward?
I believe you have to click the link and view the message. From there, you should see a button that says forward or reply. Try clicking that button.
The downfall to that is it doesn't pull up your address book, so you will manually have to type the number to the recipient.
The difference between stupidity and genius is that genius has its limits.
When you take things for granted, the things you are granted, get taken.
Even a mosquito doesn't get a pat on the back until it starts to work.
Too many people miss the silver lining because they're expecting gold.
