I have some slots left on my developers account and I will register/activate them for a small donation of 4 to get out of costs.
Your UDID will be registered for all future updates of IOS 5 so you can activate again with every new beta update.

Send an email to registerUDID@live.be and I will send you the payment instructions by reply. After receiving the payment in paypal (paypal only) I will immediately register your UDID and if necessary send you also the download links to the IOS 5 beta software.

Fastest ones will get the available slots.
