iPhone Safari Crashes

Whenever I try to log into Service Desk from my iPhone, the Safari App shuts down. I have tried rebooting the device, clearing the history and cache, none of which seems to work.

I have updated to the latest version of Service Desk and this still made no difference.

I have tried on my wife's iPhone 3G and this can successfully open the login page. it just seems to be my iPhone 4 which doesn't like the site...

I don't have any other devices I can test this with!

While not overly important, it would be nice to be able to use the site when I am away from the office, especially over the next 2 weeks when I have training courses!

Any suggestions?

Thank you,
