A few days ago we've sent the first release of one of our iPhone applications to Apple for review:

(Due to the terms & conditions of Apple's NDA we are not allowed to disclose any details regarding the app prior to its availability through the App Store...)
I've got to admit that it's quite an intriguing feeling once you have finished all the steps to finally submit Version 1.0 to Apple's App Store and wait for it to appear on millions of iPhones. Apple agrees to no service levels as to how long their review might take. Other iPhone devs have experienced anything from 4 days to 4 weeks. I'll keep you posted and will definitely publish a link once the sale kicks off! :-)
