Im curious. I've never actually owned an iPhone (Verizon.) and I'll finally be getting the 4S. Im currently on an LG Env Touch, and When I'm talking on the phone, I can also send a text, access the menus, etc etc. Is this possible on the iPhone? (I know ATT can Web browse, etc etc. Whatever) Can I be on the phone talking to someone, And while still talking, Send a text? Thanks!
