Blackra1n and push not working, should I downgrade?
I am using a 3g iphone on t-mobile, firmware 3.1.2, and push notifications are very sporadic, I'll maybe get 1 out of the 20 or so that are being sent to me in a single day. I have tried the push and youtube fix, and that did fix youtube, but push is still wonky, even tried re-installing the fix, uninstalling then installing, reinstalling my push apps after applying the fix, but nothing seems to work.
So I think my best bet is to go back to the old baseband and just use ultrasn0w like I was before. Is it possible to downgrade using an old firmware, if so, can someone tell me which firmware contains the one unlockable by ultrasn0w?
