Is it possible to tether a Blackberry to a PC without having a tethering plan from your provider? I want to use a Blackberry to provide internet to my laptop. The main service provider in my country has a unlimited internet package for Blackberry phones, however it doesn't have any tethering plans (like AT&T does in the US). So, I was wondering if there's any way that I could tether it anyway? I know it's very easy to jailbreak an iPhone and install custom software (NetShare) to tether it to a PC for wireless internet, weather or not you have a tethering plan from AT&T. Can the same be done with a Blackberry?
