3 hopefully easy questions....1) When I set my ring tone to silent but vibrate sometimes after a while it will turn the ring back on and I haven't touched any settings at all....?????? 2) How do I set a ring tone for incoming text messages? I have looked & looked & looked and cannot find out how to change it. I have missed many many text messages because I had no clue anyone had text me. I would also like to set a certain tone to certain people who text me, like you can do with incoming calls. Is that also possible? and finally 3) My facebook posts are now coming in as text messages. That setting was changed about 6 months ago as originally that's how my FB posts came to me but some very smart, informative male down at the Verizon Wireless store changed it for me but didn't tell me or show me how to change that setting....that's all for now. Thanks so much for any help...
