We have the following iDevices: iPad 3 (mine) iPhone 5 (mine) phone number ending in 10 iPad Mini (Mrs.'s) iPhone 5 (Mrs.'s) phone number ending in 11 We share a joint iCloud account. We updated all four devices to iOS 7 a couple days ago. Everything seemed to go smoothly. Until my Mrs. took her iPad Mini and, following the text prompts, one if them was related to iMessage and asked, "Did you want to use the number ending in 10" for iMessages. She was rushing through and must have hit okay. Now she is getting my text messages and ones she sends me do not come through. What happened and how can we fix it??
