Revisit 3G on iPhone AWS/Band IV Spectrum

[delonge]

After doing some research I came across this post:

Possible 3g on Tmobiles network?

User Lecram25 developed the idea that it is possible to mod the iPhone to support 3G on Band IV AWS spectrum by the following steps:

1) Purchase Triquint's Band IV PA (not available yet: TriQuint Semiconductor, Inc. - Tritium PA Duplexer Module Family)

2) Unsolder (no, a soldering iron will not work) Band II's PA from the iPhone PCB

3) Reflow/solder the new PA onto the board (x-ray to confirm!)

4) Cut the trace on that Band II's Rx path (a few millimeters from the pad)

5) Jump that trace onto Band I's Rx trace (since they share the same Rx/download frequency)

6) Hope the transceiver has a Band IV Tx/upload node/port to jump to the PA

7) One might need a few resistors or extra components (small 0402s and 0201s!) to manipulate the PA's voltage (need the Band IV datasheet to confirm)

8) Purchase 13 0402s (consisting of capacitors, inductors, and resistors) to run the low noise amplifier in Band I, IV, and VIII mode

9) One also might need to edit the firmware to use the transceiver's Band IV Tx node/port (instead of Band II's). Rx won't be an issue as it's already being used/enabled for Band I. And no, not simply playing around with plists.

Follow-up:

After checking TriQuint, it looks like a Band IV PA chip is now available: TriQuint Semiconductor, Inc. - TRITIUM PA-Duplexer Module™ Family

So is it now possible?

Others here will have more knowledge than me, so given we have more tools at our disposal than in 2010, are these theoretical steps possible now? How would you change the steps? I'm seriously considering this due to Canada's impossible market.

Any luck on this? I'm in the same boat... just can't swallow spending 100/month to stay with Rogers. Let me know if you found anything.
