My girlfriend’s boss went to New Zealand a month back. He thought he’d turned data roaming off, but actually he hadn’t. When he got home he got a bill from Telstra for over $800! That was mostly related to the constant polling and syncing that his iPhone was doing related to Exchange email (he uses Google Apps). Telstra have been nice and have offered to waive some of that, but that’s not the point. The point is, telco international data roaming charges suck!
What my girlfriend’s boss needed is an exciting new iPhone app from a smart bunch of guys in Israel called Onavo. I met up with their CEO last week at the Mobile World Congress, and in a busy networking lounge with no spare seats we pulled up some carpet and he showed me what Onavo does. And I was impressed!
