Talk:UDID

Isn't the serial 12 characters long? --rdqronos 18:14, 17 March 2012 (MDT)

Yes. Actually looking at my old iPod and new one. The old device are 11 characters and the new are 12. I don't know when it started since I only own iPod touch 2G and 4G. --Jacob 18:58, 17 March 2012 (MDT)

So then how does one calculate the hash? I tried it with the Serial+ECID+MAC+Bluetooth MAC SHA1 calculation and it was completely different... maybe someone should update this... --rdqronos 20:54, 17 March 2012 (MDT)

I can confirm it's not working. I tried with ECID in both upper/lower case, with/without leading zeroes, even in decimal. --http 07:46, 18 March 2012 (MDT)

What about with first 11 digits of the serial? --Jacob 14:50, 18 March 2012 (MDT)

Not sure what I've done wrong, but now it's working. For people still having problems: There's an app in Cydia called "UDID Calculator", which shows all relevant values. --http 16:32, 23 April 2012 (MDT)

I can confirm that it is working at least on my iPad 2 and my iPhone 4 --rud0lf77 12:15, 18 March 2012 (MDT)

What format of the ECID did you use? (I don't have Xcode handy.) Hex or dec? Leading zeroes? Upper or lower case? I was trying with my 4S, maybe it has changed again. --http 15:05, 18 March 2012 (MDT)

You can get both with redsn0w if people are wondering. Both Hex and Dec. --Dylan Laws 15:39, 18 March 2012 (MDT)

Also, what format for MAC addresses should one use? xx:xx:xx:xx:xx or xxxxxxxx --rdqronos 15:46, 18 March 2012 (MDT)

To rdqronos: The format for MAC addresses should be clear (see description) if it hasn't changed: including the colons and the letters in lower case. --http 18:56, 18 March 2012 (MDT)

Alright. Thanks --rdqronos 19:36, 19 March 2012 (MDT)

iPod touch 1G

To calculate an iPod touch 1G's UDID, shouldn't it be the Bluetooth MAC address that's "00:00:00:00:00:00," not the Wi-Fi MAC address? --Dialexio 18:51, 23 March 2012 (MDT)
