Q: Is there a way to make it so that all the imessages my phone receives are received as text messages instead?

No, they would have to be sent as texts instead of iMessages.

if that is your situation I would probably just turn iMessage off under settings > messages

Then he won't receive iMessages at all.

But if he turns off iMessages it will remove his phone from the iMessage database, and the sender's phones will send as SMS instead of iMessage.

If all the senders have the Send as SMS option on then yes.

How does an iPhone send a message to a non-iPhone? It goes as SMS, whether "Send as SMS" is on or off. Likewise, if an iPhone cannot receive iMessages because the feature is turned off this is the same as sending to a non-iPhone.

I'll have to check that, not tried it but have seen reports of difficulties sending to people who had an iPhone and then changed it.

If you turn it off, then wait for a couple of days for the database update to get to sending phones it should work. The problem is that it isn't instantaneous.

Ah, that explains it (I have no patience for that sort of thing )
