回答“I've got my firmware and TinyUmbrella...ERROR 3194”Hi William, You might not have put your device into Pwned DFU mode. (Google how to if you haven't). The 5.1.1 software is not the latest firmware by Apple, and they do not like their users changing to different iOS's apart from the latest version. Pwned DFU allows you to bypass this safeguard put in by Apple. There are other reasons for this and I will cover them if this does not work, but this seems to be the common issue for people who have not looked into the world of jailbreaking and unlocking. (04.10.01 is your baseband, in case you didn't know)
回答“Why my iPhone has gray lines?”The LCD could be a cheap £5.00 replacement part bought off eBay. These displays do work but can have faults, like uneven lighting around the screen and dead pixels. The display could be a cheap one.
回答“Does my 3GS have two different microphones? Which one do I replace?”There is only one microphone on the iPhone 3GS, at the bottom of the device and there are also 2 speakers of the iPhone, the earpiece on the iPhone display assembly, and the speaker, which is near the microphone. The speaker and the microphone are attached to the dock connector assembly. I really have no idea why the microphone only works when on speaker, maybe try a software restore or maybe replace the Dock Connector Assembly?
