Unlock after Jailbreak = Loss of Data?

[Kansas784]

Quick question. I have an Iphone 16gb on 1.1.3. I have activated it and jailbroke it but now I would like to unlock it to use with other carriers. If I connect it back up with Ziphone and unlock it, will it erase my data that I already have on it i.e. music, videos, apps, settings ect.

Thanks in advance

Check if you can find bootneuter in installer. It should unlock your phone.

Never mind. Don't do this.
Just read a warning on some site.

Warning ! You must be on fw 1.1.4 to be able to bootneuter your bootloader with BootNeuter !!
