What are the low-power oscillator part numbers and manufacturers? Do they have standby / enable pins? What's the I/O voltage standard for this type of board? What's the manuf & PN of the mini connectors seen all around the board?

Hi CEL (NEC?)- I'm assuming given the forum that this is about the RF side of things (there are other on/off switches). For cellular it is a Murata module w/ SAWx2 filters and what is likely a SP9T GaAs switch for Mode/Tx-Rx switching. David Carey / dcarey@teardown.com / 512.338.3654

It's NXP's OM3805, a variant of PCF50635/33.

Hey, what about the switches used in the 3G iPhone? Whose are they?

Not much to what seems the obvious shared antenna for GPS, WiFi, and BT. Just a little bent strip of metal a couple cm. long, down at the opposite end from the planar internal antenna for cellular comms.

Thanks Prognosticator! This document is very much a "live" one: note the UPDATE regarding the WCDMA transceiver. Thanks for helping to fill in the gaps.

Here is a link to the last PA. You have posted the 2X versions instead of the 3X versions, but they are probably very similar. http://www.triquint.com/docs/o/TQM616025/tqm616025.pdf
