Can I release without having to restore?

Question

Hello.

 

I moved to Portugal in the gigs, so he wanted to release the iPhone (iPhone 4, iOS 4.3.3) so that when you go there and put a Portuguese card day to return to Spain

 

I've been staying with what might release by IMEI.

I read that if done well, then I have iTunes to restore your iPhone. Did this restoration would have to do it every time I change the SIM?

 

Would it be possible to release without restoring? I have things I do not like to lose, do not know if I could recover with a restoration (jailbreak, ios 4.3 ... I like the mobile as we have now and do not want to be doing the jailbreak and everything else each time change country ...: S)

 

What do you advise me to do?

 

Thank you. A greeting.

Answer 1

After released by imei, try putting the SIM of another operator and connect your iphone to your PC, let itunes detects and disconnect, wait 10 seconds and reattach it and itunes should release it without restoring.

This I have done in 3 iphones 4S and it has worked.

Answer 2

Ok, but two things:

- That I have to do every time you change the card (each time you change country)?

- If I release, for example, today, I can run my card smoothly connecting to itunes or anything, until you come to Portugal in January?
