But if my IMEI doesn't starts with 99xxxxxxxxxxxxxxxx, is then possible to submit unlock here -
worldwide iphone 5 unlock?
Thank you for uderstanding my problem.
I don't know.
All I can tell you is that there is no reported
valid unlock (domestic/international) for Sprint in any reputable forum I have been a part of.
You can find endless posts on unlocks for AT&T and Verizon and even T-Mobile, but everything I've read says you cannot do this for Sprint.
Lastly, the way this works is that Apple maintains a database of unlocked IMEI/ESNs. Your IMEI/ESN gets added to this database, your iPhone is unlocked. But Sprint will not allow ANY of it's IMEI/ESNs to be entered into the database for unlocked domestic use. If you managed somehow to get one in there it'd probably be spotted very quickly as it'd be the ONLY Sprint one in there.
In any case, I don't see Sprint listed on that site you named. But if you want to be a test subject for us, then report back after they've taken your money.
