Has anyone seen HSPA+ on their Inspire? Go to Settings, About phone, Network, and check mobile network type. I've never had anything but HSDPA, even though I'm smack in the middle of a 4G coverage area defined by AT&T. Could it be the 3G sims most people have been given? I'm trying to get a hold of one of the new 4G sims, but have had no luck yet.
