It goes beyond just that from what I hear. I hear clicking address links will still be tied to the other nav app. So to navigate using Google Navigation u may have to enter the address manually. Some ppl may find that an inconvenience considering it didnt have to be like this.
As long as u can still use Google Nav it should be be ok. I never tried Bing so I cant comment on that. I dont use it on my PC. Never had a reason to.
And I see where the OP is coming from too. No locked bootloader, nice gpu.... These Samsung phones are the new Droids. The new Droids on Verizon are Motorola Milestones now.
