iPhone 3G continues to "improve" August 29th, 2008
Apple releases firmware version 2.0.2 to combat the issue that plague users, that of having dropped calls and unreliable 3G connections. Speculations lead to a problem with the iPhone 3G hardware but I doubt if Apple will admit if it is indeed a hardware glitch. However, an independent Swedish group of engineers at Bluetest tested the iPhone 3G hardware and found it within the same range as other 3G mobile phones from other vendors. This leads us to speculate that it is the network that is the problem. However, Apple still released version 2.0.2 and aggressively suggests that users upgrade to this new firmware.
With every new firmware upgrade, one thing gets broken – the jailbreak. :) However, fast on the heels of every new firmware upgrade, the folks at iPhone Dev releases new versions of their PWNAGE tools to jailbreak it.
Whilst jailbreaking, in theory, voids your warranty (you can always do a full restore), it is sometimes necessary specially with Apple's AppStore criteria prior to an application's release. Imagine not having Qik for video streaming. :)
My personal take on this, I have my iPhone 3G in pristine, legit 2.0.2 firmware since it is under warranty from Globe Telecoms, Philippines. My unofficially launched iPhone 2G, otoh, has been jailbroken for Qik. :)
