Apple launched the iPhone 4 in 17 additional countries today, causing another round of debate over whether or not the iPhone 4′s external antenna design is flawed or not. A UK consulting firm says its tests show the “death grip” problem is real, and “significantly” worse for the iPhone 4 than other smartphones. A review from Norway is less critical, suggesting the iPhone 4 gets better signal than competing phones and may be victim to AT&T’s less “robust” wireless network.

Shortly after the iPhone 4 began shipping in the US last month, users started to notice a problem: gripping the device in a certain way led to signal attenuation and, in some cases, dropped calls or poor data connections. While Apple CEO Steve Jobs was somewhat dismissive of the issue early on, testing conclusively demonstrated that the iPhone 4 had a higher signal attenuation than other smartphones when bridging a small gap on the lower left side of the device’s stainless steel bezel.
