Motorola Cliq :: Cliq Not Recognizing SIM Card?

The screen has been cracked recently, so my brother took it upon himself to buy me a Cliq (MB200) from someone off CraigsList for my birthday. I am not sure if this is the route I would had gone but it's not like he can take it back now. Luckily it is a Cliq with a T-Mobile emblem on it, which is my carrier, so there shouldnt be any problems. And it appears to be in excellent condition.OK, time to transfer the SIM card.First, we cannot get the newly purchased Cliq to recgognize my SIM card. It is an old T-Mo SIM card that has been transferred from A Samsung T-719 purchased in 2007 to a BB Pearl to a BB Curve and then to the Cliq2 bought in 2011. I do have newer SIM cards that have never been opened or activated, so that could be an option. But the SIM works fine in my Cliq2. But in the newly purchased Cliq we immediately get the "Please insert SIM card" message on the screen.Yes, we did do a factory reset and then re-tested the SIM.Wi-Fi works.We were curious if the SIM Card can't be read until we go through the Motoblur registration.Also, can the Motoblur info just be transferred from the Cliq2 to the SIM Card or SD Card so I don't have to login on the newly purchased Cliq?I forgot my Motoblur password and it is registered with an inactive email address, so a password recovery via email is not an option. Should I just open a new Motoblur account? Will it let me connect the same emails and social media accounts as the old Motoblur account?
