Arrived from US into Sydney Thursday morning. Inside terminal, turn on
Blackberry 7210 and it picks up Telstra and I get all my incoming emails. Then flight continues on to Melbourne. Again, pick up new emails as soon as we land in Melbourne.

On the way into Melbourne, email quits working and only brings in in-coming once in the afternoon. Last night at 2am, I go to network and scan
aailable network, get Optus, register with it, and get incoming and out-going emails. Since then, nothing, regardless of whether it's Telstra, Optus, or Vodaphone. Have tried using gprs and gsm. Phone works. The blackbery has the send and receive signals, but no incoming or outgoing email. And the mlife works part of the time. Account is with ATT. Any ideas? Thanks
