Might as well wait...
Over here on this side of The Pond we've got SFA for a 5G availability, making getting a 5G phone a bit of a stupid idea.
Verizon offers the fastest 5G speeds (something like a few hundred MBps) but only to zero-point-zero-four percent of the nation. T-Mobile has much lower speeds (~50MBps IIRC) and only to 19% of North America. AT&T had speeds even worse & only to 10% of the U.S.A... So unless you lived in one of the few spots that had it at all, you were better off sticking with a 4G/4GLTE unit & getting a signal at all.
I'd like 5G with the highest speeds possible, but until the various carriers pull their heads out of their asses & actualy deliver what our tax dollars have paid for a zillion times over, there's no point to buying a 5G device.
