I've had this WP7 phone for almost a week and have noticed that the exchange mail (at least exchange) is not pushing real time. As someone who also owns a Razr and iPhone (I know:blush, I intended to use this phone purely for business. But the push/exchange email is not reliable at all (works flawless on Razr on same network, same settings). I've tried everything (proper settings, updated software, resets,e etc.)--sometimes it pushes, other times it does not. Anyone else experiencing? I want to love this phone but if I can't get exchange server to work on a Windows phone...
