How to recover Notes from my iPhone 4s?

I didn't realize that Apple shares Notes in the Cloud, so I deleted them from my mother's device. But then I found that the notes were gone on my device. I have some very important notes that I need to retrieve. I looked at some software that would get it back, but have no money to pay for it.

I think your top smartphone has a backup! So please go to its settings and search for what you lost! Also an authorized apple store may help you as a good deed sign+guaranty?! A trustable expert friend may also help you to recover them with the pc and apps!

Do not panic. The most important thing you need to do now is DO NOT add any files into your iPhone before the recovery is done.
And then you can use a professional iPhone data recovery tool to get back iPhone notes as soon as possible.
The tool I'd love to recommend to you is Hodo iPhone 4S Data Recovery. It is able to recover almost any kind of iPhone files including photos, videos, notes and more.
It can recover iPhone lost files in two ways: directly from iPhone & recover files from iTunes Backup.
PS: what is more important, remember to do backup next time in case of data recovery.

Instantly and freely restore lost sms from iPhone, I think this guide will work for you, make it clear by yourself.

If you have an iTunes backup of the deleted notes, you can restore the notes with iTunes free.
1. Open iTunes and right click on your phone's name.
2. Select "Restore from Backup". If you don't have an iTunes backup, iTunes will not offer this option.
3. Use the drop-down menu to select a backup then click "Restore".
4. Wait till the backup is restored. It depends how many files you have restored. So please wait patiently.
5. Click "OK".
6. Wait while the Apple iPhone 5 is synced.
7. When the restoration is done, you can disconnect your iPhone from the computer.

If this does not work for you, you may need to pay for a third-party tool to recover notes from iPhone directly.
