My boyfriend uses a BB and loves Blackberry Messenger. I'd like to be able to use Google Talk on my Hero and his BB in lieu of SMS for chatting with him while at work, so that I can turn my phone on Airplane mode with only wifi on to save my battery (signal is terrible in my office) My concern is that I'm not sure if Google Talk is always connected like his BBM seems to be. Anyone have any insight on this? I see that "Automatically Log In" is an option....but say for instance we don't chat for a few days and he decides to send me a message. Will it be pushed to my phone?
