Just an update on this.... iPhone 1.1.3 has a WiFi bug that prevents connections to ad-hoc networks (computer-to-computer). This confused me for a few days this week and I was disappointed to have lost my MetaTrader on iPhone. However everything still works perfectly as long as the iPhone and computer are both wirelessly connected to a standard wireless router (NOT a personal network created by your computer). Everything should also still work fine over the Internet via EDGE/WiFi and your dedicated I.P. if you went that route, although your connection will probably be less responsive.
VNSea is still rockin'!!
