Between our GPS and Russia's GLONASS plus over time some improvement in GPS hardware, it's already pretty easy and fast to lock on to plenty of satellites. If we end up with three GPS satellite systems and hardware/software that talks to all of them ... wow.

It seems like many (most?) newer smartphones can use the GLONASS satellites; my new one definitely does, though you might have to go into system settings to (for whatever reason) tell it that you want to use those satellites too.
