I don't think there is any fix coming soon. They are probably working on getting the new iOS working for the upcoming iPhone.
Apple isn't paying attention to this either. Last time I upgraded the result was battery drain took a hit, cellular connection getting dropped, the AT&T bar generally used to be 3 to 4, got reduced to 2 to 3. An update came few months later, and this was a secondary issue to them, as their upgrade I think targetted mostly security.
I think Apple need to send strong signal to Director of iOS development, like they did to the guy who left after iPhone 4 came to the market with improperly positioned antenna. Apple did not acknowledge that earlier, but with lot of noise, started to give advise to people to hold the phone in a different manner, and something to do with the cases. Then soon came the 4S where they rewired & position the antenna correctly. The guy who was responsible was canned in a very short time after the public noise.
Every update in iOS, there is always a f**k up to something important.
