Most developers will get around to updating their apps for OS7 eventually. The one thing you want to hang onto is your license/product keys. I had BerryWeather on my 9650 that I paid for and when I went to the 9930 I simply had to download the OS7 version and enter my license key that I bought way back when. If you paid for apps that aren't yet compatible with OS7 shoot the developer an email and ask about any time frame.
