You can buy handsets with TEA on ebay, you can even buy TEA firmware
files for certain handsets on ebay (TEA1, TEA2 and TEA3) are available.

I don't know if selling the firmware files is perfectly legal and I
don't want to discuss this. But having a handset with TEA firmware
does not help much, at least not for Motorola handsets. The reason
is that there seems to be no obvious way to put know keys into the
handset. From what I heared there seems to exist some sort of
obfuscated/encrypted key file which can transfer keys to a handset
but I never seen one of those files.

If anyone knows more details and/or has a key file with know keys,
please let me know.

Best regards,
  Dieter
