Well if you are tied to a particular network all you have to do is call up the customer help line of the service provider and ask them for the unlocking code, which will be provided to you for a nominal amount of money.
You can also get the unlock code through online..........i will suggest the website. which is doing good service .....you can approach this website.

The best way to unlock your Blackberry is to buy unlock codes from a trusted vendor.
Search internet for mobile phone unlocking websites. You will come across a thousand websites who can do this. Choose which ever you like. Do look for price comparisons and the unlocking instructions.
Recheck the Model number- Network to which your phone is locked to and the IMEI number before placing an order. If you made any mistakes in these details these people will never give you a refund!!
One more thing, before placing an order ask them about the conditions for getting a full refund in the case of a code failure! Think and make a wise decision. I have personally bought the code for my Blackberry Storm from unlockgenie.com. It is because they have good reviews on most of the mobile phone forums. I got my phone unlocked successfully from that website. I think their codes don't fail. The web link for the above mentioned web site is http://unlockgenie.com

I have changed from nokia to blackberry bold. all my contacts on sd card - how can I import them to the blackberry contacts


You have the easiest option to copy all your contacts to your sim card and then copy it back to black berry. In order to do this you simply have to go to your phone book options and in the settgings you will find copy contacts to sim and then put the same sim in black berry and select copy contacts from sim.If your contacts are more than the capacity of your sim then you can select the contacts to copy and you have to do this twice or thrice depending on your sim's memory.

Will my blackberry 8310 sim card transfer to blackberry smartphone? just curious


SimCards are definitely meant to be transferred from one phone to another on GSM networks. You only need to ensure that the new blackberry you plan to get is "Global-Capable," meaning that it does have a physical slot for a SIM-Card, and if you plan on travelling Internationally, bue sure to contact your carrier prior to travel to have your phone provisioned correctly in the switch.
