Help Small Picture Message on Tmobile

[Rosapink]

I switched my carrier to Tmobile and i ran into some minor problems but now theres something really annoying happening: whenever i receive MMS with a picture it comes really small like a thumbnail. I have researched for hours today and i am getting really frustated with this. I Know many found a fix for other phones but i havent seen a fix for INSPIRE so far. did anybody ran into the same problem and had any luck fixing it yet??
