How do I fix my iPhone with dead strip at the bottom?

Thanks for the quick reply! Just to confirm, the most top layer is the digitizer, then the LCD screen is below it? Is there anything in between the digitizer in top and the LCD?

As well, the digitizer is the part where it detects input, and the LCD is just the display, right?

I see that the ifixit link is $99.99, and the other one not as expensive. Are there reasons why the ifixit link is just so much more expensive?

Thanks.

You are right with your description. The digitizer is the part that detects your touch, LCD just does the display. the difference in price is that ifixit is really guarantees their products and do stand behind what they are selling. Not a fly-by-night company. I guess just like anything else in life, you get what you pay for. Sometimes the cheaper parts are okay as well. Your call on that one ;-) The only thing I really really strongly suggest is that you get the assembly. It can be a royal PITA to piece it together if you try the separate pieces. Just my 2cents....hope this helps.

Would you suggest buying these parts in eBay or some other cheaper alternative? $20 and $100 is really a huge difference.

Referring to what you said earlier, you said it might be a pain if I buy each part individually. Would it still be the same if I bought only the digiizer and LCD display (because that's all that's broken)?

What if I just replaced those two parts? Would it make it easier or cheaper?

Not much cheaper,but definitely way more difficult. If you buy an assembly you can truly get it done in minutes. The individual parts are a bit cheaper, but you will have to transplant the home button (PITA) and the ear piece speaker. So don't throw anything away until you are done with your repair. I personally prefer to get the assembly and be done with it....;-) but that is just my preference.

just to put a penny or 2 in... I buy them separate, no problem really but I have done a fair few, my first repair was a broken screen and it truly wasn't so hard... just remember to keep the hard metal backing and the frame that has the home button and earpiece on. You don't need to take them off etc, but you need to make sure that you get double sided adhesive/tape with your digitiser to stick the digitiser back on to midframe. As OT3 says the complete assembly saves drama, buying the 2 screens saves money.
