Apple Inc has been sued by iPhone customers in at least three complaints related to antenna problems on its newest model. Apple launched the iPhone 4 last week to a huge groundswell of demand. But the launch was also plagued by complaints from some customers about poor call reception on the device when they held it in a certain way. The problems have been a hot topic on the Internet, but it is unclear how many people have been affected. The issue does not seem to have hurt iPhone sales so far. Apple sold 1.7 million new iPhones in the first three days.
