I have just written a guide how to Speed up the GPRS connection over at my S60blog. Check it out if you?re interested to read more:

DNS has no impact on streaming consistency. DNS servers will only impact the initial connection to a link. After that, there is no more involvement.
 
On top of that, S60 Internet Radio doesn't even support DNS, you have to enter IP addresses to the streams. So this change shouldn't even affect that app to begin with.
 
DNS setings will NOT affect your mspeed results, video download speeds, or anything else related to transfer rates. And running a single test on each is meaningless, as variable as the networks are. I ran three tests on each and got the following:

Standard settings: 221, 225, 233k.
OpenDNS: 227, 227, 168k.
 
However; should you choose to ignore what people here say that this doesn't do anything then I might recommend you start here:

...and then work your way up to being a Network Administrator.

cha-ching!
 
Nobody is claiming that it "doesn't do anything." What is being said is this has nothing to do with transfer rates.

Determining whether changing your DNS servers actually impacts the overall performance of your browsing session would be something that would be a bit more difficult to measure on a cell phone.
 
agreed. It might make the page loading faster the first time u load the page, but there won't be any change in your actual download/upload speeds due to this.
 
It's more fun as a joke if you're a nerd and actually have (or have seen) the massive size of just the first volume in hardcover. Probably not a lot of people around here...

(wow I suddenly feel old)
 
I'm not worthy, I'm not worthy! *bows* Did you actually just get out of your chair and go measure that? heh... I totally gave up buying dead trees years ago and donated most of my library to work or friends or whatever. The past couple years it's so much easier to google and find a PDF or HTML doc and search it for what you need.

PS: I guess I should expect nothing less from a guy who's nick is 'xargs', probably even more obscure to the folks on HoFo. I, however, use it daily - usually with the -0 switch coming from find -print0.
 
I did actually get up out of my chair, but I didn't go so far as to bring a ruler... I just eyballed them.
To be honest, this is probably the first time I've touched my Stevens books in five years or more. I guess I just can't bring myself to get rid of them, even though, as you say, it's usually easier to find what you need online.
You're the first person to comment that they actually knew what it was...
 
Why the GPRS tweak will not work and why it is dangerous to change your DNS server addr.

A DNS server is basically used to convert a hostname/url like ?www.abhishta.net? to a corresponding I.P. address like ?192.168.1.1″. It will not improve loading times, download rates in any way.

But some users reported an increase in their browsing speeds. How did this happen? Let me explain it to you in brief:

A GSM system uses TDM or Time division Multiplexing, wherein each user transmits in predefined time slots. Since GPRS/EDGE is an overlay over GSM, it works in the same way. Initially, the network starts your connection by assigning you a single slot with the most conservative data rate. As it sees that your bandwidth requirement increases, it will try to increase your data rate by decreasing the coding rate (you still transmit in a single slot) if the channel conditions permit. However, if that is not enough, it will then try and assign you extra time slots to transmit, provided the network is not busy. Thus, your data rate increases gradually as you start your packet data session. So if you started your speed test with the network default settings and found your data rate to be say, 50kbps and then if you changed your DNS settings and re-ran the test, the network knowing that you have an active data connection, will allocate additional resources to you. That?s why you see an immediate increase in your speeds.

I would STRONGLY recommend people to keep the DNS server to the network default as a bad DNS server could lead to DNS spoofing.

Let us take the example of a bank, say for example, Bank of America. Its url is ?www.bankofamerica.com? and its actual IP address might be 129.2.24.23 (hypothetical IP address). And this is available in your DNS server. Now, someone comes along and says, change your DNS server to blah blah and you will get better speeds. Trusting him, you do it. In the new DNS server, www.bankofamerica.com is now mapped to IP address 129.24.56.20 which belongs to a hacker. The hacker runs a web server from that IP address and hosts a spoofed version of the bank of america website. And on that duplicate website, the moment you enter your username and password, it gets stored into the hacker?s database and your identity is compromised.
