I've been receiving this error when trying to access my new dev site, but ONLY on devices running iOS 6.0.1 using Safari:

PDOException: SQLSTATE[HY000] [2002] Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) in lock_may_be_available() (line 167 of /var/www/html/dev/mysiteinfohere/includes/lock.inc)

The site loads fine from other devices, and even loads on iOS 6.0.1 using Chrome. Any ideas why the new iOS would be a problem in particular?

Thanks so much,
