[b7ish]

Hi Frens!

I have a iphone 4 with firmware 4.3.5 and bb 04.10, would you please suggest me how to upgrade my iphone 4 on iOS 5.0.1 instead of 5.1 as I want to have unthered jailbreak? Also, I wan to preserve my basband. How can I do that?

I can't vouch for it, so do it at your own risk, but this site seems to give details on how it can be done.

Thank you for suggestion, however, I would like to upgrade my iphone 4 to iOS 5.0.1 instead of 5.1 and preserving my basband. Any reliable suggestion or guidance?

Ah ok, well try following this guide then. Again, I can't vouch for it, so do it at your own risk, but it's a pretty tried-and-tested method.

I am grateful for your quick response, however, I heard Apple stopped signing iOS 5.0.1 but I still can upgrade custom iOS 5.0.1 to my iphone?

As I understand it, yes, Apple stopped signing iOS 5.0.1, but I thought that meant that you were unable to downgrade from 5.1 to 5.0.1. I THINK you should still be able to upgrade to 5.0.1 just fine. But as I've been saying throughout, I'm not 100% sure, but that's what I think.
