to downgrade from ios 5.1 to 5.0.1 can we just put the phone in dfu mode and then restore to 5.0.1??
iam on ios 5.0 but i want to test ios 5.1 for my "outgoing call no sound" problem.
can some one explain how to??
?
 
From what I understand you need to have a developer contract w/ Apple to test iOS 5.1 beta. If you're already a developer... then I appologize. :-) Then yes... downgrading to 5.0.1 is that simple. DFU mode & restore via iTunes since 5.0.1 is the current firmware release.
 
Yeah that's what I mean for the 4S my iPhone 4 got water damaged and broke so I now have the 4S I'm waiting for a dev team to release the jailbreak for the A5 based devices as I really want my iPad2 jail broken aswell :(
 
i forgot to mention it, i have got a Iphone 4S is it then also the same?

yes i have a dev contract with apple but its new a couple of days now :)
 
Yes... it will work the same for the 4S. I'm not certain how developers, yourself, download beta versions... but reverting back to 5.0.1 is simple as a restore via iTunes.
