I have Iphone 4S , I was using Viber for messaging. Hit update Apps without thinking, started to update Viber app as well. I cannot lose some of the vital messages. I paused the download and turned off the phone. How can I cancel this process for not to lose my messages?
I do not believe this is possible. If you had backed up the phone to a computer you could restore the phone after it finished update and you would be back at the old version and perhaps your messages would be backed up also.
