Infinite Flight for iOS RC1 has been pushed to Test Flight yesterday, our beta testers are hard at work and have reported a few issues that we've worked already.
About Windows Phone 7, we haven't forgotten you guys :) We'll start beta testing the WP7 version as soon as we ship the iOS bits. Beta should be quick as we have been playing with our Mango Phones during all this time, so we don't expect any major issues.
Thanks your patience as we work through the last remaining issues!
