Most of the developers never planned for the extra markets. As I understand it they must redeploy the apps and select the new markets they want to be in. I have mailed several of my missing app developers and asked them to resubmit with all countries selected. In case you wonder... I mailed, Amazon Kindle, Tripit, TuneIn Radio and Twitter. Only tripit answered that they only support the US market - which is strange regarding that i downloaded it from the British Marketplace (pre Mango) and especially as my friends with Android and iPhone devices can download it here :-( But I downloaded My Trips instead
