Physics II works fine on my iPhone 3G (waiting for the maybe soon iPhone 5), but Physics I will not sync into the phone, even though it appears in the app view of the sync window for the phone. After syncing, restarting, and resyncing several times, I tried the "support site", which will let me hire a speaker to speak to my company about the quality of Wolfram products and support, but the site does not allow actually asking questions. Reminds me of Microsoft Word 3, which MS put out without beta testing. I tend not to buy anything from companies that dont respect customers enough to test their products. Are you listening now, Wolfram?
