I'm brand new to this website, so I'm sorry if I'm asking questions that have already been answered. My family has service with Nextel, I understand that only 7100i and 7520 are compatible. I'm looking to get one or both of these models...used. If i do get them used, I know I need to make sure it comes with a sim card. Then do I just take it to my local Nextel/Sprint store with my old sim cards, and they can switch the info ? Is that all ? Do i need to contact Nextel itself and tell them of my switch ? will i get charged a fee ?

Also, does anyone know if I can access Juno mail ( i know, who has juno anymore ) through either one of these blackberrys ?

any opinions on which one is more user friendly would help too.

Thanks !
