Ok, I have a sidekick 3 with the unlimited sidekick services. A friend of mine just recently gave me his Blackberry 7100t cuz he got a new phone. I know I can just insert my sim card in the blackberry and use it for the text messaging and phone use. I was wondering what would I have to do to continue to use the Instant messaging and email when i decide to use the blackberry. Would I have to get the blackberry services also? Thanks
