So, since this has T-Mobile and AT&T 3G bands, as a T-Mobile subscriber when I'm roaming on AT&T's network in a place that AT&T has 3G will I be able to use it? Up at school in Michigan (Ferris State University), T-Mobile has no service but ATT does so I'm on Edge when I'm roaming up there wondering with the bands if this will change! Thanks to anyone who responds!
