As many households do, we share the same AppleID so that we can share apps and information easily. With iOS5, now we iMessage each other for free, BUT all other iMessages that we send to other iOS5 users are also blasted out to all other iOS5 devices. My husband doesn't want to see all my texts to other people, but now there is NO WAY to send a normal text to other iOS5 users...it will only go out as an iMessage. Is the only solution to get a separate AppleID for my husband and then buy all of our apps again for him? That would be a huge pain, essentially requiring him to erase his iPhone and iPad and start over. Or do I disable iMessages for him? Is there any way to distinguish between different users within the same AppleID?
You make a separate Apple ID and just use that for iMessage (and probably iCloud, but not the iTunes Store). You can enter it at Settings > Messages > Receive At > Apple ID. You are not required to use the same Apple ID for every service on your device.
