I was listening to MacCast today at the gym and was shocked to learn about such a horrible bug in IOS/iMessage that could be causing a lot of people problems on their iPhones/iPads/iPods. The issue is that when an SMS message is sent and IOS decides to use iMessage (wifi and bypasses the mobile carrier's text system) any attachments are saved permanently in the device's database and in the backups! Even after you delete the message or the message thread, the attachments are NOT deleted. The upshot of this is that the only way to deal with it now is to jailbreak your phone. I'm not jailbreaker so I don't recommend this and I don't need or want this myself. But some i-devices have VERY constrained storage. My first iPhone (iPhone 4) had only 16 GB. My current iPad is 16 GB. Apparently Apple has not addressed this, but I see it as a major bug. What do others think?
