Yeay! I managed to decrypt the 96 character token:
# AES-ECB decrypt a 96 character iOS token -> valid 32 character token
from Crypto.Cipher import AES
import binascii
keystring = '00000000000000000000000000000000'
iostoken = '16a935db276e19b1c7bef0739f2deb7d3aca43c5e26a3c6445351cb2fb8495ea0143db63ee66b0cdff9f69917680151e'
key = bytes.fromhex(keystring)
cipher = AES.new(key, AES.MODE_ECB)
token = cipher.decrypt(bytes.fromhex(iostoken[:64]))
print(token)
# Output: b'4a447a41467058496746505541597033'
