ok i want to first download and upgrade to iso 5 beta 1 which i am pretty sure i found a web page with directions on how to do it. thats not my question though. i am currently using 4.3.5. and as many people know without shsh blobs you can't downgrade. My question is this: If I upgrade to ios 5 beta 1 and get the itunes beta do you think I would be able to downgrade from that back to lets say 4.3.3. or sooner? The reason I want to do this is to be able to unlock without using the gevey sim so I can get my data to work and not have to worry about this illegal sim. any thoughts or help would be awesome!!
