This is an extremely common glitch. Although it has not happened to me personally, a lot of people post about it. If you want to name your tama "chloe" name it "ehloe" and for "jeff" name it "leff". Then the glitch will ocurr naming your tama the right name.

You can only use a cell phone when an adult. If your tama is 2nd Generation or higher, go to the little book thingie, press family, then parents and then the middle button until you see their cell phone number!!!!
