I talked to the rep last night and I told him that my device is seeing opened security Wi-Fi network around my apartment and he said it is normal and it's OK to use it as long as you don't try to connect to a Wi-Fi network that is locked and required a password. He went on to say that it's hard find out and trace a device ID that is being connected to a Wi-Fi router. The Wi-Fi router's light may be flickering but the user can't really tell if his neighbor is using his Wi-Fi network or not, that is according to the T-Mobile rep.
I also told him that my phone is displaying uma (I noticed a letter "u" next to the number when I checked my account online.) while making a call at home and he said that's is because the device was making a call using my neighbor Wi-Fi network over the internet and it not going to use up my minutes. Again the rep said that my neighbor wouldn't see my calling information on his bill.
Just to make a long story short, the rep told me go ahead and use the neighbor's Wi-Fi network as long as it's opened the the public.
