So having read in Apple support files that they recommend that most users use the same Apple ID for both iTunes and iCloud, I've chosen my gmail address, which I was using for iTunes purchases etc. as the login for iCloud. However, I've entered my me.com address as the Apple ID (as well as email) for both iMessage and FaceTime on my iPhone. Seeing as the two are linked and are the same Apple ID (me.com being an alternate email), are there any potential problems with this and secondly, can people only iMessage or FaceTime me if they know my me.com address. Will they also be able to FaceTime using my gmail address (which is the primary one for the Apple ID)?
