Okay guys, so I've had my iphone 3g on ios4.0.2 and today when I turned it on, there was a black screen, the phone did NOT load up and it just said "Locked"

There was no "Emergency Call" or something to do. I have never had this happen before. I do use T-Mobile on this iPhone. PLEASE Help! Thank you!

restart your phone.....if that doesnt help then its a restore for you...but being careful to not upgrade your baseband..

Thank you, I've hard resetting the phone, and this time I'm able to get to my passcode, but then the "LOCKED" screen comes up. So should I restore my whole phone? It takes quite a bit of time or will this message go away? thanks!

Also any idea why this is happening?

looks likes something you installed might have caused this to happen...all i can say is if ur concerned about unlock then be careful when restoring your device...
