http://forums.androidcentral.com – I have done some research but with no anvil. Is their away to replace S-voice with Google now? For voice dialing over bluetooth in my car and every other aspect? I could find a how to for ICS unlocked phones but this is the ATT (stock) not rooted currently. Thanks in advance! (HowTos)
