MMS upgrade for Sprint Blackberry Curve 8330?

[Brad]

I recently got a BlackBerry (NSDQ: RIMM) Curve 8330 through Sprint (NYSE: S) and it does not have MMS texting. After hearing that there was an upgrade that would allow MMS texting, I went to the mall and asked the person working at a Sprint kiosk if they knew anything about the upgrade. He told me to attach my Blackberry to my computer using the USB cord that came with it and go to blackberry.com and there would be a link somewhere on that website to get the upgrade. I searched the web site and could not find the link anywhere. Could anyone tell me anything about the upgrade or how to get it, if there even is one? Could anyone send me a link to the web page where the upgrade is, if it exists?
By the way, I am fully aware that Verizon (NYSE: VZ) Blackberry 8330's have MMS texting as well as some other carriers, but I am looking for an answer specifically for the Sprint Blackberry 8330. Thanks ahead of time for any answers.
