I know that HSPA is T-mobile 3G. And HSPA+ is T-Mobile "4G". I have the G2 and it says I'm connected to HSDPA when I go into settings-about phone-status. So what is that??? Please clarify if I'm messing anything up or explain something I'm missing. And yes I know that it only shows an H for when I'm connected to 3G and the same H for 4G. Thank you =)
