Screw identification help iPhone 4

Does anybody have a layout of what screws go into which hole?

There are several obvious locations for the washers and broad head screws but a majority of them are a mystery if you don't keep track of them.

I had an orderly system set up but I tipped my tray and it's all jumbled. On top of that I lost a handful of tiny screws so I ordered a replacement kit.

I want to make sure i'm doing it right this time and based on just numeric descriptions "2.5mm" i'm unable to determine which screw is what.

Is this a good question?

The title of this is "iPhone 4" but the list of screws is for "Verizon 4S" and some screw sizes will differ. The screws in the iPhone 4 can be the same length but some differ in diameter. A calliper is instrumental in defining the sizes.

Also, I'd like to suggest using rubbing alcohol and a screen cleaning cloth for cleaning connections. It doesn't leave a film and evaporates quickly, so no need to "dry" after use. Just don't use excessive amounts.

Cheers and good luck!!!

All I can say is to maybe look back at the teardown and compare size & shape.

I recommend using this next time:
