I see you have to create a log in using your PIN and ESN... I am getting a replacement phone in days does this mean my settings will break/ and or my login will break, once i get the new phone?
You can also do this directly from your phone. If you go to setup, then email settings, it will list your existing email accounts. Highlight the email account, hit the blackberry key, then filters. Add a filter and when the from address contains your email address and choose the option not to forward to your device. Once you save you should stop seeing your sent messages sent to your phone.
I don't send/receive gmail to my blackberry e-mail... it clutters the inbox. instead, I recommend downloading google's gmail application from m.google.com.
