Huge leap in BW speed going from TP to TP2, any idea whats going on?

[pesok]

I've had about 15 different HTC devices since 2002 and one of my main concerns(even obsession) was always improving the download speed on all of them. When i finally got TP2(swap for TP1) recently i have immediatly noticed that i no longer have interuptions for buffering when listening to my favorite programs on WunderRadio or Resco radio(BBC mostly) as well as youtube videos played flawlesly when compared to my previous (customised with all imaginable speed hacks) TP(1). When unlocker was released i was ready to unlock my TP2 and flash custom ROM as i always have on all my previous HTC's. After downloading the unlocker i dont know why but i decided to test speed on Sprint stock(6.1) ROM before actually unlocking it. When i saw the numbers that http://www.dslreports.com/mspeed spit out at me i almost fell out of my chair. After that I kept testing and retesting everywhere for few days and unbeleavably it was not a one time fluke. The best result is posted in my signature(done on PRL 60656 with Sprint stock 6.1(no speed tweaks whatsoever), tethering(for test purposes only) on Ubuntu 9.10(Jaunty)), results in Vista and W7 are much lower but i am still averaging half of speed in signature which is about twice the best speed that i ever got on TP(or still getting on my Sprint Diamond(custom 6.5 ROM-same Ubuntu). Needless to say i am happy as a chainik and decided to put off unlocking and stick with stock ROM for now for fear of loosing this miracle. No more laggy youtube or annoying buffering messages for me! Anyone else experienced this?
