Hey, quick question. I'm considering getting a 3gs, as I only have a 2g right now. But can I use its voice control to play an artist on the iPhone when my iPhone is locked? If so, how? Do I press the home button or can I press the Mic button on my headphones? And last question (same topic, assuming I can), can I voice control an artist when my iPhone is in my pocket? (Example: Phone is in my pocket and I press the mic button on my headphones and say Play Linkin Park) Thanks a lot! This question is a deciding factor in me getting the 3gs.
