For people who had been waiting since January to watch TV on their iPhones, price doesn’t seem to have been an object…The most expensive item in the store, by far, is Lextech Labs’ iRa Pro, an $899.99 application that displays live video feeds from up to 6 security cameras simultaneously. Apparently its users find iRa Pro worth the price. Six of seven reviewers gave it either four stars or five. The seventh complained about the price and gave it only one.
