Hack a Blackberry 9700 Bold to access internet without BlackBerry data service

[I kept this post for long as Draft; thought I shud l publish; ]
Playing with the Blackberry 9700 from Sujoy who was not using it because it cost a lot to enable Blackberry service with the Operators who are offering BB services.

So I picked it up just to see why should such a device left unused just because some kinda service is not available or bcz its expensive. Following are the things what I am currently doing with it :

Setting the Internet connection without the Blackberry data service :
First of all you have to set up your tcp settings. In your BlackBerry menu go to => Options - Advanced Options - TCP and enter your APN information for your GSM Service.You can ask your customer care for the APN information.When you finish the settings you need a browser to surf the net. The best one is Opera Mini Browser. You download the Opera Browser to your BlackBerry and in the Opera Browser menu you go through automatic network setup. Once the Opera Browser finds out your settings you are ready to surf the net from you BlackBerry for free. (Excluding standart connection charges- for the GPRS/Edge from your GSM service provider)

Happy, browsing then without paying the BB service :P.
