My son has been doing really well with his new cell phone, but recently he's hooked up with a girl who seems to never sleep and I have more than once found him late at night texting away. Not good. I have talked with him, but I'd also like to work with AT&T Wireless to establish blackout hours on his phone service during which time he cannot send or receive texts. Is that possible?

My son has just come home from his uncle's house with a new iPod. Very nice. Full of a wide variety of music, some of which I don't want him to listen to. He says "ya can't get rid of any songs without removing them all" but I don't believe him. Is there some way to remove a half-dozen of the worst songs without redoing everything on the iPod Touch?

I just realized that my daughter has my iTunes account password because I got a receipt for about $25 worth of purchases that I'm sure I didn't make. I don't even like Eminem, Lil Wayne and don't even know who Wisin & Yandel are... ?

I'm dealing with my daughter, but it seems reasonable to also change my iTunes Store password. Except I have absolutely no idea how to do that. Help! How do I change my iTunes account password?

My kids keep sneaking my iPad and playing games on it without my permission. I know, I know, it's a parenting issue, not a technology issue, but I just feel that if in addition to talking with them about honesty, trust and honor, if I can add a password to the iPad to prevent easy access, I'd have a backup if they were still being sneaky. I'm sure I can set a password up on my iPad, but how?

I've got a real problem, Dave. My college-age son had a party in my house while my younger children and I were on a trip and now I find that my house is a venue in Foursquare called "Party House". I don't want that. At all! How can I delete my house as a Foursquare venue??

Rather to my surprise, I found out through a stray email that my son had signed up for a MySpace account. He's 11 and he doesn't have permission to do so. As part of his punishment I am going to delete his account and since it's just a few days old, I'm wondering if I can simply ignore it and have it go away or if there's something special I need to do?

In his sermon last weekend, our pastor talked briefly about the dangers of our teen children sexting. He didn't go into it and I've no clue what it's all about, but I want to know more about sexting before I talk with her so I don't seem completely clueless. Help?

I've gone to the Consumer Electronics Show for years, and generally the innovations there are because something is bigger, faster or brighter (think TVs and audio gear). Occasionally you'll find a company that's rethought a common object -- like, say, an iPod dock -- and done good things with it, but mostly it's the same stuff you saw the previous year, just refined and reengineered.

For 2009 the commodity item at the show seems to have been headphones, ear buds and other personal listening devices to improve your iPod, cell phone, Gameboy, PSP, laptop and other handheld device listening experience. I came home with a half-dozen different ones!

The one that I found brilliant, however, wasn't the one with skulls on the ends (though that was cool), or the one with personalizable earbud ends (again, cool idea) or even the lower priced noise-reducing units. The winner in my book was the listening devices from iHearSafe that limit the max volume of what you're hearing...
