Can you put a rogers sim card into a t-mobile sidekick lx (unlocked)?

[Courtney Sierra]

and if so, what features would work in Canada?

I also need a few of these answered too
-Would the text messages be in the lx's software format?
-Can you connect the lx to your computer, and transfer ringtones bought online?
-If you put in your micro SD card, will all your contacts be transfered, along with all your information?
- Would all the features in the following wireless phone package work on the lx? and if so, is there an even better Rogers (NYSE: RCI) plan? http://www.rogers.com/web/content/wireless-plans/essentials?content10=12_every_call#start
- Would previously bought ringtones on the rogers wireless internet service work on the sidekick?
-I am aware that the internet & IM won't work in Canada, but can you get the internet service from Rogers?

Please, answers are needed, even if you dont have the answers too all, it would be greaty appreciated.
