My Problem

The speaker started making crackling noises and was working intermittently until it finally died.

My Fix

The tip of the pentalobe screwdriver was too small and would not engage. Had to file the tip down. The plastic opening tools are pretty much single use.

My Advice

Definitely use the replacement phillips screws. If the screwdriver does not firmly engage, don't keep turning or you'll round the head. File down the tip to be higher on the taper. It should only take a light touch to turn the screws.

My Problem

Speaker was dead. It started making a crackling sound and progessively got worse until it was no longer functional. The phone had never been dropped and no liquid spills.

My Fix

The repair went smoother then I anticipated. No hidden surprises due to the well written guide.

My Advice

I rarely made any contact with the metals of the phone. I made sure to use the tweezers as much as possible. As a result I did not have to clean the metals as suggested in the guide.

Ensure you are using the correct tools. iFixit provided all of the necessary tools for cheap.

Lastly, do not tighten the srews too tight. They are very delicate screws.

My Problem

My Iphone 4 speaker enclosure got splashed by some liquid and stopped working. I no longer have a valid warranty, so a return to Apple tech support would have cost me a small fortune. Decided to get the parts from Ifixit and do the replacement myself, and thought of replacing the quickly waning battery to save the time of another operation.

My Fix

The guides were detailed and comprehensive, and it was quite a pain free process. it took me slightly longer than I expected, partly due to the screws being so tiny. I did not have an Ipod opening tool, but managed ok with my fingernails and a pair of tweezers.

Now my Iphone is as good as new!

My Advice

I had some problem with wi-fi reception after the repair, and had to open up my iphone again. the problem was the 4.8 screw attaching the wi-fi antenna, so make sure it is secured well and tight. The wi-fi reception is fine after this minor follow up.

My Problem

The sound suddenly stopped working on my iPhone's speaker.

My Fix

The repair went very smoothly. I followed the step-by-step instructions and had no problems at all. The iPhone 4 is much easier to work on than the iPhone 3.

My Advice

If you don't have one already, don't forget the tiny torx screwdriver you'll need to get the iPhone 4 open.
