I'm trying to test my web app on my phone, but for some reason, I am no longer seeing the latest version when on the phone when I deploy the app (for testing via ShortURL). I have confirmed the build is being successfully uploaded by modifying the initial page and opening the URL on my PC browser, but the Nokia browser on the phone is still showing me the version I uploaded at the end of last week.
I've tried clearing the personal data from the nokia browser, but that had no effect, so the only other thing I can think of is that the phone is caching the app itself, somewhere. Does anyone have any idea where it is and how I can delete it, or if something else is going on here?
Phone is a Nokia C2-02, and I'm using the latest version of the Nokia Browser (I deleted and redownloaded it earlier, but it had no effect), if that makes any difference.

Thanks.
