I must concur. I love 3.5G. my BB died and I my phone company wanted to charge me around 450 dollars for a new BB with a new contract, or about 100 dollars for an HTC Touch Dual, so I went with the dual. HSPDA
Loving it. Also, I must admit, the browser isn't that great, but this browser, sorry BB, still does laps over the BB browser.
But honestly, I just love browsing really fast. I also have Data intensive apps like Skype, and since I have unlimited data, i've been skyping A LOT. I actually have to recharge my new 2400mah battery twice a day for that reason :D haha.
but the NEW BB's are HSPDA enabled so that's awesome
