iOS users, Could you recommend me an app which has the following features?
Ability to load previous chats from GMail Chat (NOT FROM SAVED MESSAGES OF THE APP). To be more specific, The app should have the ability to load last (at least a few) messages by searching from the gtalk history from Google account and NOT* by retrieving it from the iOS devices itself (like saved conversations in the iOS device or in iCloud).
*Push Notifications even if the app is running in the background only (Not when closed)
*Photo sharing & Location sharing (Like a google maps link to be sent to the receiver)
*Getting the last message (if any) if the connection is lost in b/w.
