Whoops... fixed! :)

You're right, we don't have pentalobe bits in our bit driver kit just yet. However, we've been working on a new revision of the kit that among other improvements includes pentalobe bits. The specific bit we used in the teardown was one of our preproduction samples. Unfortunately I don't have a good ETA for when we'll have these pentalobe bits available, but we are actively working on the project.

Great writing, thanks for showing how to fix your phone!

Do you have the weights for the component pieces in the step 31 photo?

I added the weights to the step. On my scale, the total weight of the iPad came out to 697 grams. That's definitely more than the .68 kg quoted in the Apple specs.

Cita de Jeff:

I haven't seen any mention of the microphone, but my assumption is that this is part of the headphone jack assembly (that small hole directly adjacent to the headphone jack).

Yes, the microphone is right next to the headphone jack, and the signal goes through the same ribbon cable as the headphone jack.

Cita de Jasiu:

How much does the bottom case weigh ? Battery + glass + lcd is 494g. So it should be about 150g. Is it ?

I just weighed the aluminum back by itself. It's 138 grams, which is almost exactly 20% of the iPad's total weight.

Cita de Travis Funk:

Is iFixit going to carry the T3? how about the glass?

It appears that iPad screws may actually be T4. I used a T3 bit, but others have reported success with a T4 bit. Fortunately, we include both T3 and T4 bits in the 54-piece kit that we already sell. We don't have the iPad glass yet, but we're definitely hoping to offer it in the near future. It looks like at least one person needs a replacement glass already.

Cita de Thomas J:

Who manufactured the display?

We don't know who manufactured the display from the unit in this teardown. If anyone knows, we'd love a tip. On another iPad we opened, the LCD markings were different and the panel was clearly manufactured by LG.

Have you been able to identify the materials or surfaces that they inspect on iPhones and now, iPads?

The iPad does feature liquid damage indicators. Apple will deny warranty coverage if these are activated (they turn pink after coming in contact with moisture). There appear to be two of these on the iPad, one in the headphone jack and one near the dock connector.

Cita de Ove Celius:

Why not just use a big suction cup? It worked perfect on my iPhone.

On the iPhone 3G and 3GS, Apple was nice enough to use visible screws instead of tabs. Since the iPad lacks screws and is held together with tabs, I think it's unlikely you could get the iPad apart with a single suction cup. We'll be working on figuring out the least invasive way to get your iPad opened up.
