No, it is not.
No
I have no idea. You can go on the blackberry website and find out and by the way, You are talking about either blackberry curve or blackberry torch right?
Depends what Blackberry you have - I think I read that the 7250, Curve and Bold have wireless internet. Blackberry's website provides instructions on how to set it up.
I think that it is not free, but you should Google it!
You would need to have a blackberry plan if you wanted to use things like BlackBerry internet and messenger etc.
will there be a blackberry curve 4g?
U have to activate the blackberry service otherwise u will not be able to acces the internet via moble network.
you may have to go on the internet to download it
Depends on the carrier, and the plan you chose.
Yes you do have to get it in order to activate your phone.
The blackberry curve has Wifi, so if u are in a free Wifi zone then you will be able to browse the internet for free. Also, if you select a contract with a good data plan then it may be free depending on what you chose at the time of purchase.
