I am very happy in using this interesting short audio messages feature using iMessage of my Apple device. But I am very much worried about the storage of these messages.

Yesterday I have deleted few pictures from my iPhone by mistake. Is there any way to recover the photos or pictures deleted by mistake from my iPhone? Where do I find the deleted images? Is there any feature available which helps me to hide these images in my device without deleting them?

I had clicked few photos of a recent party with my new iPhone. I am not able to find the photos taken with my Apple’s iphone. I checked them in the Albums tab, but could not find even one there.

I love the Apple’s context sensitive text but I feel that it slows them when I type. I am very curious to know whether this Apple’s feature can be switched off when not needed. I would also like to know whether this interesting feature can be put in the background making it available simultaneously.
