BES/Exchange Hosting

Hi, I have a quick question about BES/Exchange Hosting. My situation is backwards from most people. My company doesn't offer BES, and I want to get hosting so that I can use my Blackberry like it was meant to be used. So, I will have to have my personal e-mail as the BES account. Will I still be able to send and receive my other e-mails (Gmail/Company E-mail) on the device the way that I currently do using BIS or am I stuck with only the BES account?

Also, I'm currently using Outlook and monitoring several accounts that I don't want to receive on the Blackberry. Will I be able to move all of my Outlook info to the Exchange version or will I be forced to use a seperate version of Outlook for those e-mail addresses?

Sorry for the noob questions, but I'm unfamiliar with these services.

I'd love to hear hosting recommendations, too! Thanks
