I have my iPhone and have always synced it with my iTunes account on my Macbook pro. My wife also has and iPhone but she never synced it to anything and needed to do so but did not want to lose her stuff. I did a search on how to sync her phone to my iTunes and I ended up doing something to the format of iTunes but can not remember what and now I can not find the link that showed me how to do it. Now when I try to sync my phone it says it has be connected to another computer and wants to erase my stuff. When I open iTunes, at the top of iTunes instead of it saying iTunes it say Argentina so somewhere I changed that. I think this may be causing me to not be able to sync my phone. Does anyone know how to fix this and get it back to original. Thanks and hope everything I wrote made sense.
