Many VPN's have special procedures for China, so before chucking yours out the window, contact the technical support desk for those workarounds. If your VPN is corporate not private, they should be well aware of how to help you out. Some services have special procedures for use on mobile devices.
Assuming you are using a private service: If your VPN is a PPTP-type VPN, those are not reliable for China. Many VPN companies have both SSL and PPTP types of services, with the latter being cheaper. If your VPN is really a proxy server inaccurately calling itself a VPN, those are also no longer reliable for China.
