Help, Unlocking 6030?

I need to unlock my brothers T Mobile Nokia 6030 Type RM75 for the United States so I can use it with my AT&T service.
Nokia 6030 Type RM75
IMEI 010892/00/041482/9

Also are the steps listed below correct for the actual unlocking(got it from one of NoLimit04's postings)

Thank you all in advance!!

 

Remove Your Sim Card, Power The Phone On
Press # From The (Insert Sim) Screen
Enter codes WITHOUT spaces.
Press * 3 times fast for (p)
Press * 4 times fast for (w)
Press * 2 times fast for (+)

 

#pw+908 352 421 643 477+7#

 

Thank you,
I put in the code and after entering # nothing happened.. Nothing, the code is just sitting there, shouldn't something happen telling me bad code or go back to the insert simm screen? I did insert my AT&T simm card but still get the restriction code needed screen.

 

1. Insert a non accepted sim, most times it will show "Phone Restricted"
2. Press the UNDO option
3. You should see a box that says enter restriction code.
4. Enter the code given and then press (OK)
#pw+205 295 427 375 555+7#

 

I tried that and got a "code error" message then it goes back to the "Enter restriction code" again..

 

What the code did you tried?

I gave you this(For 6030-usa-T-Mobile-010892000414829)-

MCCRASH, I did use the code you gave me.. Should I give Celtic71's code posted earlier in this thread?(#pw+908 352 421 643 477+7#) I understand you only get a limited amount of chances and do not want waste them... Also I'm a bit confused as why his code is different then yours using the same original IMEI code?

 

You can use what you want.
#pw+908 352 421 643 477+7#-this code if this phone locked to AT&T.

But you wroteI need to unlock my brothers T Mobile Nokia 6030... and this code that i gave you-#pw+205 295 427 375 555+7#-if
this phone locked to T-Mobile.

If didnt work,read once more-

The Phone is presently Locked to "T-Mobile", I want to unlock it to use with AT&T....

 

Itsnot important,where you want to unlock.
Important is only-where is phone locked to.

 

So which one is correct for a T Mobile cell phone in the US which I would like unlocked to use with our AT&T Service??

Tried it again without the simm card in and it worked..
Thank You!!!!
