Hi - I'm going to be leaving on a cross country trip from CA to DC to Va on Amtrak. I have a Blackberry Curve 8900. Will I be able to get on the Internet during the train trip? I have an on-line business and need to send attachments when I reply to email messages that I get on my phone. Under normal circumstances at home I can. I have T-Mobile with WiFi and a media subscription (I think that's what you call it). Thanks for any help you can give me.:)
