This is the boat that a lot of developers are in, but it is particularly frustrating for Ilium Software. Ilium has sold two well-respected applications -- eWallet and ListPro -- for Palm OS and Windows Mobile devices for years, and has a number of other commercial and free mobile applications on the market.
According to Ilium spokesperson Ellen Craw, eWallet has been "in the queue" at Apple for over two weeks, and they can't get any word from App Store personnel on when their highly anticipated app will actually appear online. The comments in Ilium's blog are particularly revealing, as longtime customers are also frustrated by the black hole at Apple.
Having used Ilium's products before, I'm waiting for both ListPro and eWallet to show up in the store to fill those niches on my iPhone. What other great products are being held up by Apple? We'd love to know!
