The Chad

OK here's what I have:

Nokia N91 4 gigabyte model. Purchased 2 yrs ago from an individual in Hawaii. Worked great untill yesterday.

Here's the Problem:

I was talking on the phone like normal and the phone cut off to the "NOKIA" screen. I cut off the phone and turned it back on. Then the message popped up stating: "startup failed contact retailer." and "SIM Card Registration Failed".

Of course no one at the local AT&T store knows anything about the phone due to it being from over-seas.

I did some googling and found that you can do a "hard boot" manually by pushing the *, 3, and green send key when powering up...all at the same time. This is supposed to bring it back to the factory settings.

Without a SIM card the phone will now start up but everything (and writing) is in Chinese/some kind of script ( i have no clue what language).

I can't seem to find anything allowing me to change the default language setting. Anyone have any info as to how to re-set the phone again and keep the US spec settings???? Thanks in advance!
