Hi,

Who set the price for BES?
By RIM or intermidiate Service providers?
What is the advantage/disadvantage if we buy BES via our Service provider?
or What is the advantage/disadvantage if we buy BES directly via RIM?

Why there is price different between providers and RIM?

A lot of carriers will give you a free copy of BES if you buy 10+ handhelds. You may want to contact your local service provider to see if they have that offer avaliable.

What u mean by "free copy of BES" ?
Is it trial version?

RIM' price for BES is 3999$
But some providers ask for more, like 4500$

Why they ask for that much?
Can they sell it for 4500$, and what is the logic there?

To get you to buy 10+ BB at the same time, they'll throw in a fully licensed BES. It gets you to commit to their service. That's where the money is.

Providers can sell BES for whatever they want. You might as well buy from RIM.

RIM sets the price. Carriers sell it and get a comission on the sale. The price is the same (usually) but Carriers could sell for more.

What's the logic? isn't it obvious? make more money?

Blackberry Express 4.1 is free.

Agreed. It's a capitalist industry.
