Little bit of a bug report:

I was helping someone sign up for FT today using the iPhone app. Noticed a couple of bugs:

1. On the sign-up screen (where you enter a username, password, etc.), the keyboard covers the bottom third or so of the fields, so you can't see what you're typing in those fields.
2. No UI feedback after submitting the sign-up page. It just shows the spinning data-transmission circle in the top menu bar (or whatever it's called on an iPhone--next to the 3G logo) and then the data-transmission circle disappears, leaving you on the sign-up page without a submit button. Not intuitive what to do next, especially since the activation email was a couple minutes delayed (leaving us unsure if the sign-up request went through).
3. Even after tapping the activation link in the email, opening the iPhone app still displayed the sign-up button in the upper-right corner of the home screen. It wasn't clear if the app recognized us as being signed in until we noticed the red bar with the "welcome [username]" in tiny text.
4. The welcome note that popped up in the app after we opened it after activating the account shows the raw HTML markup for the links, so the "Looking for a place to make your first post? How about in this thread:" shows up with <a href="http://www.flyertalk.com/forum/thread.html">an HTML tag</a> instead of a clickable hyperlink.

Then being dumped on the home screen with a list of new threads instead of forums is kind of jarring--it gives no sense of the organizational scheme of FlyerTalk (this became apparent as I was trying to walk this new user through FT). I would suggest considering making the forum listing the default home page and retitle the current "Home" screen to something like "Hot Topics" or "New Threads" or "Subscriptions" or something.

Hope the thread content view is fixed in the next version to show marked-up text instead of the raw BBCode, which is also confusing for new members.

But still #1 on my priority list is synchronization of the "first unread post" function.
