    • 在开始之前，将您的iPhone电池放电低于25％。 已充电的锂离子电池如遇意外穿刺，可能会起火和/或爆炸。

    • 在开始拆卸前关闭iPhone的电源。

    • 您的iPhone 4后盖可能有两个＃000十字螺丝或苹果的5点“Pentalobe”螺丝（第二张图）。 检查你有哪些螺丝，并确保你也有正确的螺丝刀，以拆下它们。

    • 拆卸两个3.6毫米或000 pentalobe菲利普斯#螺丝旁边的基座连接器。

    • 拆卸Pentalobe螺丝时，确保驱动器安装牢固，非常容易剥离。

    • Remove the following five screws securing the wi-fi antenna to to the logic board:

    • One 2.3 mm Phillips

    • Two 1.6 mm Phillips

    • One 1.4 mm Phillips

    • One 4.8 mm Phillips

    • When re-assembling, start off with replacing the 4.8 mm Philips screw first, then the 2.3 mm. This is to ensure there is no mix-up, and avoid rendering the LCD and digitizer useless.

    • Also make sure to put the long 4.8 mm Philips back in correctly when reassembling. This is the ground for the wi-fi antenna and is often the culprit if you are having bad wi-fi reception after reassembly.

    • Use an iPod opening tool to slightly lift the top edge of the wi-fi antenna away from the logic board.

    • Use the tip of a spudger to pull the wi-fi retaining clips away from the inner frame.

    • Remove the wi-fi antenna from the iPhone. Make sure you don't lose the metal clips on the top of the cover where the 4.8mm screw attaches or the 4.8mm screw. That's the primary reason for abnormal Wi-Fi performance after the reassembly.

    • Before reassembly, be sure to clean all metal-to-metal contact points on the connector cover with a de-greaser such as Windex. The oils on your fingers have the potential to cause wireless interference issues. Do not clean the connectors themselves with Windex.

The wifi antenna has a small clip connecting the black antenna to the logic board.

Its very small and apparently easy to loose as i never even saw mine. If you loose it you will not have a good wifi signal untill its replaced.

I purchased an iPhone 4 GSM new/sealed from an Apple Store in July 2010

and never needed to connect to multiple Wi-Fi networks until recently.

When I would go from a known Wi-Fi connection to another one,

I would need to go into Settings to reconnect each time.

I figured that I needed to replace the Wi-Fi antenna.

When I took off the back panel, I discovered that the 4.8mm Phillips screw

that grounds the Wi-Fi antenna is not present. So, you might want to first

check that the screw is there and properly secured.
