I have a Blackberry Bold 9000 (AT&T) that gets App Error 523 a few times a day. It resets and recovers fine, but it's a major hassle. I've tried everything I can find on the forums, including wiping the device clean using Jl Cmder and reinstalling the OS. I have the most recent versions of the OS and DM. Blackberry's website says it's a known issue with no current solution. Any ideas? Thanks for your help!
