Probably the cheapest UDID activation available... USD$1.99!
You need to register your iPhone's UDID in order to try out the new iPhone OS 4 Beta.
I can register your UDID on my Developer Account and provide you with a download link for your device (check compability) so you can try out the 100+ new features of iPhone OS 4 before the official release!
What you need to do:
PM me the number of iPhones you need activated and I'll reply ASAP. Payment is simple: USD$1.99 via PayPal. I'm not doing this for profit, I only want to recoup the cost of a Dev Account (poor uni student)!
How to check your UDID:
To find your iPhone's UDID, just plug it into your computer and wait until iTunes recognizes it. Select your phone from the Devices list in iTunes and click the "Summary" tab. To see your UDID, click on the word "serial number" beside the picture of the iPhone. You should see the word "identifer" and an alphanumeric string – this is your UDID.
To copy it, just press command + C on your Mac's keyboard (or control + C in Windows). (Source: TUAW)
This does not provide access to a full developer account. Please wait for my confirmation PM (usually within 1 day) before you install the new OS on your iPhone. You will need access to a Mac running iTunes 9.1 to perform the update.
Thank you! :D
