Howdy texmarvin. Well, partner; Metro PCS's platform, on their handsets, are BREW supported; and Sprint, is J2ME (Java Micro Edition). Therefore, ANY Sprint or J2ME enabled handset, shouldn't allow MMS, WAP browsing, or any other Java enabled apps., to work on Metro PCS's network. The flash should only allow voice and text. You can call to a Metro PCD store, and I'm positive they'll tell you the same thing.
