I know, I know. I'm growing a bit tired of having to sift through e-mails from iPhone app developers who have seen their fruits of labor ( big or small ) rejected by Apple's team of mobile software scrutinizers myself too. But I keep being amazed by the reasons Cupertino puts forward for not allowing apps into the App Store, and this is another classic example: TweetPhoto , a TwitPic competitor that lets Twitter users share photos quickly and easily, saw its first ever iPhone app barred from entry because its logo is slightly reminiscent of a Polaroid photograph .
