My Blackberry 6230 TM unlocked has no browser configuration.
Hi, Please do Hard Reset. To perform a hard reset, complete the following steps:
1) Remove the battery cover from the back of the BlackBerry smartphone.
2) Remove the battery, and then reinsert it after a few seconds.
3) Replace the battery cover.
Please Check if the Browser icon is hidden. If it is hide then please unhide.
Please check if the service book is available, if not then please contact your service provider to send the service book.
Please check if Blackberry services are active.
If once you Unlocke the handset using Unlock code, then you can use any sim, even if you restart then you dont have to unlock it again.
I hope this information will be helpfull to you.
