Hey, I just found my closet iphone 3gs yesterday. it was running ios 5.0.1(jailbroken unteathered and unlocked). I saw apple claiming battery issue fixed in ios 5.1 and/or 5.1.1 and I tried to preserve baseband and upgrade. I can upgrade to 5.1 but redsnow saying it is teathered; I can not upgrade to ios 5.1.1 as itunes keep telling me "the device is not eligable for the firmware". I even tried to restore to stock 5.1.1 and itunes displayed the same warning...

I checked hosts file(s) and there is no entry for gs.apple.com.

I am running mac os x 10.8 with most recent itunes.

So my question is:
1. Is there a way to unteather jailbroken 5.1?
2. Is there any known issue of upgrading to ios 5.1.1 with latest MAC/itunes?
3. Should I try to upgrade to 5.1.1? OR Does it really fix the battery issue? OR I should downgrade back to 5.0.1?
