Dear gguhin,
I see in the forum that you have been helpful to several people in unlocking their Audiovox 4100. I would be grateful if you helped me too...please.
I bought the brand new phone off Ebay USA and the company claimed that it was unlockecd...when i got it, i realised that it was locked by AT&T.
I downloaded the file rilgsm.dll and the instructions that you sent to someone else. At the beginning of the intructions it says
"...as long as the IMEI you provided me is the one from your phone and is correct........
please do the following:"

but considering i have not given you an IMEI number do you know whether it will still unlock my phone...? My IMEI number is
IMEI xxxxxxxxxxx35

I hope you will be able to help me out... Thanks and looking forward to hearing from you..

Regards,

Vikram
