iOS 4.3.3 to iOS 6.1.3

[Ahson]

Hello everyone,
My uncle just came to me with his old laggy iPhone 3Gs which wont work properly it's contract finished last month and he is using some other network since then... and he wants to try iOS 6 for a change!

I have two questions!

1. if i Make a back up of iOS4 to iTunes will I be able to restore it on iOS6...
only two things he want to are -Notes and -Contacts... will they be restored to iOS6? if not is there a way around!

2. I don't how he is using other network but does it mean his phone is factory unlocked now and I can update it without worrying about having it locked!
he didn't call his network provider for unlock!
should I update?

1) A backup of an iOS can always be used on an iOS of the same threshold or of a later version, so yes, you should be able to restore it.

2) You can always hacktivate it if anything

1) Backup of your iOS 4 will work on latest version of iOS or of a later version too. So you can restore it later on your phone.
2) If your uncle is using another sim in the phone and the contract period had been expired than it might probably unlocked already.
