I have an issue.* I upgraded to the 4Gs, gave my wife my Phone 4 and plan to use her old 3Gs as an iPod touch for my son.* Here's the issue I'm running into.* I created an iCloud email for my son in order to use iMessage for free texting.* The 3Gs which has been upgraded to ios 5 still shows my wife's phone number as an option to receive iMessages at.* Obviously this is a problem because if I send a text to my wife or my son it goes to BOTH phones.* I've removed the sim card from the 3Gs and even deleted the phone number from the 3Gs but it does not remove her phone number.* You also cannot delete her phone number in the iMessage options for receiving texts.* * Will I have to set the phone up as new in order to correct this issue?
