Cisco wireless networking issue with mobile phones

Got a really, really odd scenario occurring at work at the moment, which I cannot for the life of me work out the reason behind.

We have three WiFi networks, two hidden SSID's one for internal clients, one for guests (with breakout to the interwebs only), and one for iPhones (long story, but essentially we end up using the wireless network in the cleansing and refurbishment process), this iPhone network is unsecure and broadcast, but can only break out to a pre-defined list of sites and IP addresses, and has no link to internal systems other than the fact that it runs off the same 8 AP's using the same Cisco 4402 Wireless Lan Controller.

Basically, the phones will connect fine, and if can visit literally anywhere except anywhere owned by apple.com. The phones appear to load the headers (or sometimes if you are lucky, some unformatted content), and then just give up. I thought this was possibly an anomaly with iPhones, but a random selection of phones (nokia N95's, HTC WinMo phones, etc) all exhibit the same problem.

I have tried locking the radios down to just 802.11b/g, 802.11g and even have tried adding static routing to the SSID on the controller, nothing works. So I tried connecting a phone to one of the hidden WLANs, same problem exists.

Laptops and desktops can connect to any of the WLANs (including the iPhone one) and visit the problematic *.apple.com sites without fail.

What in gods name can I check next, it's driving me nuts!

Help!
 
What software are you running on the wlc? We're just putting in 5508's with a WCS which will run our Corp and guest network. I connected my iPhone and iPad to the guest one and it works fine once authenticated. That's running the latest version of 6 (might upgrade to 7 soon as we're not quite live yet....
But then we're not filtering sites, just applying a qos policy to the guest one to rate limit guests so they won't hog our Internet bandwidth with streaming and the like
 
It's running Version 4.2.112.0. There is no issue with anything other than what appears to be apple sites.

Very odd.
 
I'm not at work at the mo, but can re-check it in a few days - we're still putting it all in (currently waiting for an Internet pipe to be delivered to a dc at the moment) - once that's in, I should be able to test a bit more freely as I've got to commission it properly and we were hitting some odd dhcp things with the guest access when we did it in the lab.

Any reason why you wouldn't consider upgrading the wlc code to 6?
 
You sure it's not the website itself and something on it being incompatible? If a lappy or soemthign elseo n the same WLAN can access it all fine then I don't see a problem with the infrastructure side, Id have thought it was something on the website the devices cant handle?

You'd think so, but the apple site not being available to iPhones? It's deff working from my house, so it could well be a bug or an mtu type issue.

Have you got any qos policies deployed?
