Does enabling Track my Iphone increase my phone bill?

I have prepaid. A few days ago, I got some credit but it simply disappeared, and I hardly did anything! I think enabling Location Services might have something to do with it. What do you think? What could be the reasons?

How to hook up another router to my home network?

Ok here's the situation. I have a modem/router (wired &wireless) from my ISP (Comcast) which my husband has downstairs in his man cave so he can play his game (Xbox, PS3) and have his Wi-Fi signal for his iPhone. Now I'm upstairs and only connected via wireless. My laptop gets an ok signal but my phone barely gets anything & this is all in my room which is directly above him, in other parts of the house it's virtually non-existent. We have another router that is our own. Can I hook it up upstairs so that my wireless signal is stronger up there? And if I can, will it affect his signal? God forbid the game lags, it will be a problem lol. So if anyone can help me, I'd greatly appreciate it.
