Apple 3G iPhone Network Instability Issue Blamed to Incorrect Power Control Algorithm in Firmware Version 2.0蘋果iPhone的3G網絡不穩定問題歸咎於不正確的功率控制算法在2.0版固件
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.雖然蘋果公司的3G iPhone手機已經越來越重視，但仍然有許多用戶不滿意的業績尤其是在3G網絡的穩定。 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.以前的症狀歸咎於以劣英飛凌的3G芯片，但現在似乎有一種新的景象轉移注意軟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.如果這是事實，即將舉行的固件2.1版很可能是能夠修復，而不需要大規模召回與混亂的硬件返工。
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.據大約草擬的症狀是由於錯誤的軟件設置在iPhone的固件有可能影響到實際接收到的信號強度計算，並最終要求更多的權力從AT ＆ T公司的基站比什麼是需要建立一個3G連接。 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.由於沒有基站優化的iPhone手機具體地說，它會導致連接下降和網絡的不穩定尤其是當基站不能滿足需要的電力需求為3G的部隊它回落到EDGE網絡。 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.如果沒有最近發布的版本2.0.2固件更新將能夠解決這一問題，但根據實際用戶的反饋，反而不利於除了能夠解決一些軟件問題，如緩慢的滾動和打字的速度。
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.但願這是實際的根源和即將推出的固件2.1版本將能夠糾正它，而不需要任何硬件返工。
