Apple’s iPhone 4 officially goes on sale in less than 24 hours from now but the screw-driver-wielding folks at iFixit have not only managed to get hold of a unit but have also torn it apart with skill that only they seem to posses. With this teardown, there are officially no secrets left to be known about what makes the Godphone’s fourth avatar tick.
Some of the key take-aways from the teardown:
While Apple claims the internal storage memory to be 32 GB (the higher-end version), it is actually 29.06 GB with 28.77 GB of it available to users. The iPhone 4 gets it juice from a 1420 mAh Lithium Polymer battery, which according to Apple should give about 7 hours of talktime on a 3G network and 14 hours on a 2G network. It has 512 MB of RAM, which is double of what is currently available on both the iPhone 3GS and the iPad. 
The iPhone 4 might get warm on the right side on long usage as the entire logic board is set on that side rather than spreading it across the casing. This has been done to make space for a bigger battery. Apple has integrated the UMTS, GSM, Wi-Fi, Bluetooth and GPS antennas into the stainless steel frame for better reception quality, a point that Steve Jobs had stressed upon during his introduction keynote at WWDC.
iFixit claims that Apple’s A4 processor is actually a 1 GHz Samsung Cortex A8 core, the same processor that has been used in the iPad and Samsung is using in the Wave! Now, that’s saying a lot about the Wave. What’s more, the gyroscope, which is supposed to make motion sensing gaming more fun, is not yet commercially available and Apple probably is the first vendor to use it. We’re not surprised, considering the number of iPhone 4 shipments Apple will achieve in the remaining five months or so this year.
Rest of the stuff is either pretty technical or things that you probably already know about. Either way, feel free to hit iFixit for many more pictures and technicalities.
