Hey Rob!
I am wondering if there will be a leak of the developer copy of ios5 on the internet somewhere? I am dying to get my hands on it!!

Hi Laura,
Yes you can get a hold of it and install with out a dev account.
Gizmodo - had this Article on how to do it.
And more info here from osXdaily.
However neither show you where to download the files - just what to do once you do find them on the web.
To find the file to download go here.
All I can say is best of luck - and I can not recommend you installing the app without a dev account. You never know what will / can happen. Note: do not update to iOS 5 with the above method if you travel at all and / or need your Phone for work reasons.
Regards,
