FAQ: Is my iPhone eWallet information backed up?
Yes, the information in eWallet on your iPhone, iPad or iPod touch is backed up by iTunes when you sync.
However, the iTunes backup process is completely independent of eWallet or any other app on your phone and is outside of our (or any other developer's) control. If something goes wrong with iTunes, you may lose your backup.
We strongly suggest that you synchronize eWallet to the Windows PC or Mac OS X version via wi-fi to keep a separate copy of your wallet file on your Desktop.
Alternatively, you can backup your encrypted wallet data file via email using the instructions HERE.
