I did a search but couldn't find an answer to this question:

I just got a new email account that I've started using on my BB. I haven't yet deleted my old account from the phone yet because I'm wondering about BB Messenger. I have a lot of contacts on there of which I've added or been added via email address. If I switch the address programmed in my phone will I lose these contacts and have to re-add them? Or once they are added are they forever with me on this phone no matter how many email switch I make?

Thanks for your help.

It should have no effect.
