Hello every one,

I recently have a used BB 8300 unlock (AT&T original), Could somebody so me how to activated the internet thru Opara Mini. I know that there a thread talk about how to remove the IT Policy, but I when installed my Blackberry Desktop Manager in BIS but I till can not find the Certificate Sync icon anywhere ? and don't know how to remove it.
Please show me how to do this by steps. I used T-Mobile Sim Card now.

Thank you very much for your help !

Welcome to the BBforums.

Why do you need a certificate sync icon? You seem to be confusing 2-3 different matters: installation of Opera Mini, certificate sync and an IT Policy.

For OM, make certain you have your TCP set: What are the TCP and APN settings? - BlackBerryFAQ

Thanks for your quick respond, I did do like what you said in " What are the TCP and APN settings? - BlackBerryFAQ" but it does not work, When I click on OperaMini Icon and it's installing then " Fail to connect to internet" finally , that's why I am confused, Please advise !
Thank you.
PS: I don't pay for Data Plan with T-mobile.

With your BB powered on, remove the battery, hold a few seconds, replace and reboot.
Try again.

Sometimes OM just won't work immediately, you might need to give it a couple days. I have seen that happen with users on this forum a few times... they come back two days later and open OM and it works.

After reboot the BB and go to Opera Mini what I have on the screen is : " The Application operated has attempted to open a connection to a location inside the firewall and outside the firewall which is not allowed by your IT Policy " What shoud I do with this ? Please advise !
Thank you for your help !

You bought the BB used or off eBay?

Remove IT Policy - BlackBerryFAQ

I bought it used.

Thank you Sir.

Jsanders,
I understand all the step of Remove IT Policy but the last step "Verification" Does BB and Computer will automatic do this step or Do I need to click somewhere on Blackberry Desktop Manager in order to do the verification step in Remove IT Policy ?

Thank you very much for your help ! I hope you enjoy your day !

Nothing to do, other than look at see that you have no IT Policy (or you do have the Blank IT Policy installed).

I did the Remove IT Policy as the instructions " Remove IT Policy - BlackBerryFAQ" but my BB is still have IT policy Enable on it which is the same as its original.
Did change the TCP but nothing works with Opera Mini. What should I need to do ?

Thanks

Then you probably haven't removed the IT Policy from the device, or like some few other users, Opera Mini just won't work for you.

I Know it still have the IT Policy but why the instruction that you provided won't work with me ? could you please show me how ?
Thanks

can anyone give me the unlocing software for 8300
