Just wanted to post about a problem my dad has been having with HSDPA on his Vario 2.
Changing DNS made the "Finding Page" alot quicker however the connection is still VERY unreliable and sometimes pages don't load at all.
One thing I noticed is that the HSDPA signal is constantly at around 2 bars and if left connected for a while you could pick it up and it'd go really quick, the speedtests say 1.1Mbps and it all looks good for about 10 minutes until it goes slow again.
Anyway what seemed to also be happening is that the phone could not make up its mind wether to use GPRS or HSDPA so I'm guessing the signal isn't great (I'm in Derby) or the ROM version isn't handling things very well.
For now we've found a setting in the network options to force the Vario 2 to always use GPRS and it's fast and responsive and reliable thus far. The HSPDA speeds would have been nice, for what my dad uses it for tho it's more than enough, I'm just hoping the HSDPA is sorted out by Feb when it comes time for me to upgrade from my MiniS.
So to summarise if you're having problems with the internet on your Vario 2 (T-Mobile) it may be worth cutting back to GPRS for the sheer reliability of it always being there when you need a page... if you have awesome HSDPA signal then I hate you...
