Hi Blackjack II users!

I need help with my AT&T Blackjack II.
It was working fine until it suddenly refused to boot properly.
Now, whenever I power up the phone, it will greet me with the AT&T 3G animated splash screen & then stay at the at&t logo for an indefinite period of time.
When it times out, the screen stays white & finally fade off with multiple colored lines & stay white.
I noticed however that it will proceed to display part of the the Windows Mobile interface with a "SIM Failure  Unknown SIM status. (Error 0)" message if I leave it there for a long time, at least 20-30 minutes.
It will never get beyond that point.
Please see the picture I took of the screen. If I use the Fn + # key at certain times, I will see a window where I can input up to 8 numbers, something like a SIM Unlock code.
If I hold onto the power button long enough, the animated Goodbye! splashscreen will come on & the phone will proceed to shutdown but the screen remains white.
Another observation I made is that if after I boot the phone & leave it for awhile, I can press the [CV] button & I'll hear two distinct sounds, first one is a beep followed by a something that sounds like a failed connection attempt.
Anyone knows what's wrong with my phone? Is the ROM corrupted?
Can it be restored?
When the WM6.1 is released, will I be able to reflash the ROM & fix the problem?
There's no official WM6.0 ROM that I can use to flash the ROM again, if assuming it's a ROM corruption.
Lastly, is there a bootloader mode for the BJII like the BJ or i600?
I welcome any feedback & solution to fix this problem.
Thanks!

Thanks for the suggestion.
I've already tried that & it completes successfully but the same problem returns.
It'll still stay at AT&T screen...and all the other observations I've made.
Is the phone 'dead'?

hello, I have this exact same problem with my blackjack ii.

Phone won't start; it gets stuck on the "windows mobile" splash screen, even after hard reset. After about 15 minutes of this splash screen it gets to the message with "SIM card error". Also I can't reflash the rom because activesync won't work, so I'm kinda stuck.

Take out the SIM card, get a pencil with an eraser and run the eraser over the metal of the SIM card.
Pop the SIM card back in and you should be good to go.

Mine has the same problem. I tried the hard reset many times, i also tried leaving the battery out for along periods of time, and i tried the trick with the eraser. Is there any help for my phone or is it broken for good?
