Thanks again - about 8 minutes to complete - 1 problem the Phillips screw driver sent in the kit was too big for the screws holding the battery tab, but this was not a real problem as I have a selection of Phillips screw drivers of the proper size.
The other 5-point screw driver fit just fine.
OK so I didn't do it on 2 minutes but...
Happy with the "How To" & happy with the parts order (Battery / Fixit Kit) had the iPhone 4 apart and back together in about 5 minutes.
Its going to take longer to re-calibrate the new battery "running it down less than to 10%" than it took to physically replace the battery.
Another good experience at iFixit!
