You in Montego Bay area? If so when looking out main entrance or exit of the Airport look up the hill my grandparents place is right there - beautiful sunsets.
Sorry back on topic what about ur International Roaming on your account? Just a thought since its been a full week. I'm not a tech at tmobile; but this is usually overlooked of travellers by overtired reps. Doubt its an issue but a stab in the dark. Bug Tmobile if they can't fix it then they'll forward you to RIM!
PS pickup some sugar cane & enjoy conch soup on a late sunset!
