[Q] Cisco IronPort blocks internet access for all apps – help?

Hi,
Here’s my situation – at my office they use Cisco IronPort to monitor and filter all internet requests. A transparent proxy is used on the network switches to direct port 80 traffic to the IronPort server. Initially only the browser on my phone would work as that is the only app that passes the correct authentication. All other apps fail to reach the internet. But the IronPort server can be configured to pass through a type of device if it can be identified. Using the IP address of my phone to filter the traffic logs, it seems that some apps pass “Windows Phone OS” in the data packets. And by adding “Windows Phone OS” to the IronPort exception list, those apps now work. But most apps still don’t work because they don’t include any windows phone identifier in the data packets. Can anyone provide any additional info on this subject or a possible solution?

Thanks.

Use cellular data instead of your corporate network?

Use apps that use the new socket APIs, or connect to HTTP servers running on a port other than 80?

Complain to your IT people (commoditization of IT being what it is, I'm actually surprised by this restriction)?

See if you can get them using proxy authentication instead of packet inspection for authentication purposes (WP7 supports proxy authentication on WiFi)?

Find a job with an IT infrastructure that doesn't suck?
