An Increase in Lost Messages More and more people are opting for iPhone over any other type of phone, and this means that cellular providers will not have a lot of phone records going forward. While your lawyer can gather information from Apple pertaining to a specific time and date, Apple can only provide what the company has kept. In most cases, this information is limited.
What if you use another messaging service like WhatsApp? Typically, messenger apps include conversation settings that each user can choose to save or delete. If you think that you may need to revert to a message at a later time, make sure to save any messages that you do have through any kind of messenger service (including Skype).
