iMessages on 1st Gen iPad
I have a first generation iPad running iOS 5.1.1. I would like to receive iMessages sent to my phone number on my iPad, but I don't seem to be able to add a phone number to the iMessaging settings. The Apple Store tech tells me that iOS 5.1.1 does not support receiving iMessages sent to a phone number, but sometimes iMessages sent to my phone appear on my iPad. Is it correct that iOS 5.1.1 does not support iMessaging sent to a phone number? Then why do I get them sometimes?
iPad, iOS 5.1.1
