I'm adding to this because I had something similar happen...I updated iTunes, did a backup of my Touch and then started getting updates to apps. I saw Hold Em was taking forever and I had to leave for work. Once it showed "Installing" I thought I was safe so I left the house, breaking my wifi connection. I saw later that the Hold Em icon was showing "waiting". Oops. So I got home and tried to get it going again. No luck. I saw the app update in iTunes on my computer and so downloaded it there. But then it went away. App Store on the Touch showed no updates and Hold Em as already installed. Deselecting Hold Em checkbox on Apps tab in iTunes on computer then syncing did nothing. The icon just mocked me with "Waiting" on the Touch. Then I did what was mentioned below. I held the power button for all I was worth til it showed "Slide to turn off". I did that then powered the Touch back on. No HoldEm icon. Yay, I think I'm almost there. Re-select checkbox in iTunes on computer and sync. Yep, taking awhile so it's installing to the Touch. And VOILA..it's done and back on the Touch now.
I'm gonna remember that little trick..seriously for teh reals turning the thing off! Whodathunkit?
Aw, man. One little setback: it lost my earnings. Oh well, now I'll have to play it again and again to get the winnings back up to where they were.
