No, you can't bypass that screen. The only way is get new HTC Touch Diamond unlock code and remember don't try to put wrong code again and again it will cause your phone in hard locked state. Go find new HTC unlock code then put that code in your phones. I hope my answer can help you, thank you.

Hello, what sim network in your phones? Are you still used t-mobile sim card? Or you have change that sim card before? it seems you phones unlocked and you need HTC Touch HD2 unlock code so you can access your phones again. Try call T-mobile customer service and requested HTC unlock code for your phones, this process needs 1-2 weeks before you get that unlock code and don't forget to prepare some money to pay charge from t-mobile. If you need that code immediately you also can buy unlock code from third party sites with lower price and just need to wait a couple minutes.

You need a master unlock code which can only be obtained from your cellular service provider's customer support dept. After they verify that you own the phone, they'll give you the code to unlock it. Simply enter the code on your phone's keypad.
We can't provide security codes for cell phones as we cannot verify the ownership.
