I purchased a 4s and gave my wife my 4. All is great. Took her 3Gs and updated it to 5. Wiped it and put it in the box. My boss asked if he could use it to see if he liked it before he bought one. He took it to AT&T bought a plan in his name and new #. He sent me a text this morning telling me how great it was. I told him congrats. Wife came around the corner and said she got the strangest text. It was my conversation on her her 4. ? What did I do wrong?
