thanks to everyone for their anwers to m newbie questions. I already kno so much more the service.
there is one issue I need to figure out. I will receive m Curve in a couple of days and will be activated on Rogers. but it's a T-Mobile phone and comes unlocked. so I wanna know :
1) will I need to change the o/s to use it on Rogers ? if yes, where do i get it ?
2)I'm reading about a pin release, I'm not sure what it is. but if the phone is unlocked, do I need to worry about that ?
NO to both questions. Just drop the SIM into the phone and set it up as a Rogers system. See the docs supplied with the phone, and notes on the FAQ board here for more detail.
