Apple 3G iPhone Network Instability Issue Blamed to Incorrect Power Control Algorithm in Firmware Version 2.0苹果iphone的3 G网络不稳定的问题归咎于以不正确功率控制算法在韧体版本2.0
Although Apple 3G iPhones have been getting great attention, but there are still many users that are not satisfied with its performance especially on the 3G network stability.虽然苹果公司的3 G iphones已得到高度重视，但仍然有许多用户都不满意其表现，特别是对3G网络的稳定。 Previously the symptom was blamed to inferior Infineon 3G chip but now there seems to be a new in sight that diverts the attention to software glitch in previous firmware version 2.0 and 2.0.1.以前的症状是指责，以劣势英飞凌第三代晶片，但现在似乎有一种新认为，在视线转移注意的软件故障，在以前的固件版本2.0和2.0.1 。 If this is true, the upcoming firmware version 2.1 is likely to be able to fix it without the need to massive recall with messy hardware rework.如果这是事实，即将举行的固件2.1版本很可能是能够修复它，而不需要大规模的召回与混乱，硬件返工。
According to Roughly Drafted, the symptom is due to the wrong software settings in the iPhone’s firmware that could potentially affect the actual received signal strength calculation and eventually request more power from AT&T base stations than what is needed to establish a 3G connection.根据粗略的草拟方式，症状是由于错误的软件设置，在iphone的固件可能影响实际接收的信号强度计算，并最终要求更多权力，从AT ＆ T基地台，比什么是需要建立一个第三代流动服务的连接。 Since none of the base stations are optimized for iPhones specifically, it will cause the connection drops and network instability especially when the base station can’t fulfill the power requirement needed for the 3G that forces it to fall back to EDGE network.由于没有基站优化iphones具体来说，它会导致连接下降和网络的不稳定，尤其是当基站不能满足电力的要求，需要为第三代流动服务势力，它依傍，以EDGE网络。 No word if the recently released version 2.0.2 firmware update will be able to solve the issue, but based on the actual users’ feedback, it actually doesn’t help except able to fix few software issues such as slow scrolling and typing speed.没有Word如果最近发布的版本2.0.2韧体更新，将能够解决这一问题，但基于实际用户的反馈，其实是没有帮助，除了能够修复一些软件问题，如缓慢的滚动和打字速度。
Hopefully this is the actual root cause and the upcoming firmware 2.1 version will be able to rectify it without the need of any hardware rework.希望这是实际的根源，以及即将举行的固件2.1版本将能够纠正它，而不需要任何硬件返工。
