phone? We were going to upgrade my husband's phone since it was time, but we were going to use his upgrade to get a phone for my daughter {her very first one 
}. Then, we were going to purchase a Go Phone, put the SIM card in the newly upgraded phone (an LG Xenon) and put my husband's SIM card back into his old phone. They told us at the counter that the Go Phone SIM would not work in the newly upgraded phone for 4 months' time. Why? Also, is there a way to unlock it so it will work now? She had to read a LOT of books as a goal to earn this phone, and she is heartbroken right now. Thanks in advance!
