hello,
i just bought a Blackberry 8320 on ebay.
It's a blackberry from t-mobile from Los Angeles. The seller told me the phone is unlocked and tried the phone with other simcards and it worked!
I live in the netherlands (Europe) and i'm using a Vodafone simcard, without any blackberry service. (that's not a problem for me , because i have Wifi ). The first thing i want to do is to use my blackberry! But i can't use the phone.
my phone is connecting with my Wifi network in my house , but is saying INVALID SIMCARD , and i can only make emergency calls. Here not many people are using so they don't no exactly what is going on.. but
i called a couple providers and they told me that blackberry had as double lock problem. Maybe the phone is unlocked, But the t-mobile provider still locks the phone. SO they told me to call with the american t-mobile provider and ask them for the unlock code. that's the only problem they told me and then after that i have to give that unlock number to my provider in the nehterlands. But sometimes they only give the unlock code if the phone is more that a year old, but the phone is more that a year old , so that's not the problem.

i really want to use my phone in the netherlands, but they don't no what to do.
what do i need to do? I saw on a other website that more people have this problem , but they didn't gave a solution....

which staps do i have to make?



ANY HELP IS WELCOME!!! I'M CONFUSED

First, make sure the phone is actually unlocked:

How do I determine if my BlackBerry is "unlocked"? - BlackBerryFAQ

This happened with my brother's old Rogers 8700. I bought the unlock code but still couldn't use the phone. There was a suggestion on crackberry.com on using JL_cmdr and I tried it.

Result? Fully unlocked and now using prepaid blackberry service from Indosat Mentari in Indonesia. My gf took it to Kuala Lumpur and Bangkok and we messaged one another without problems using BB messenger.

You'll need:

1) JL_cmdr (search for the link to download)
2) OS 4.5 (see 83XX board for the correct version for your phone)
4) DM 4.5 (didn't try it with any other DM)

You may also want to try installing the privacy.bin file to create a blank IT policy (also available at crackberry.com - never searched here, but it's probably around).

I tried the blank policy first and that didn't really help. So I went the JL_cmdr route. You'll need to install OS and DM 4.5 first cause the function in JL_cmdr doesn't seem to work for any other version of OS. Install and run the JL_cmdr and then plug your bb into the USB. JL_cmdr will "read" your phone and then you'll get a menu. Look for "resettofactory" and follow the instructions. Once you're done you should be able to use your phone. Keep in mind though that after you register for bb service it could take some time for your provider to register your PIN with their service. Mine had no problems and it took 24 hours over here to get it working...did not have to call Rogers to release the PIN.

The blackberry could have been from a BES environment and their IT policy could have restricted phone calls from being made. We have an IT policy that restricts phone calls from being made or received on the company's own blackberries but if the employees have a blackberry that's not provided by our company then we don't put that restriction on.

Look in the FAQ's there's a section on using JL_cmdr to delete an IT policy from the blackberry and that should resolve it.
