I recently bought my daughter an LG Rumor Touch phone and I can't block media downloads on her phone. I went to my preferences "limts and perimssions" and I don't see her phone as an option to edit. It appears to be a technical issue but I'm having trouble getting in touch with them.
its sprint way in making money, you need to sometimes complain about it to sprint customer service at *3 and tell them what you want blocked so you won't get charged extra fees. Thats what I had to do. Hope that answers your question.
