I would think much of my traffic going halfway accross the country for its gateway or worse yet, a proxy...especially when dealing with traffic that is sensitive to delay (VoIP, streaming video).

For T-Mo, it seems like the Internet2 APN routes "some peoples'" traffic thru the midwest, where the epc APN has it routing closer to the user's actual location (at least per speedtest.net).

I meant w.r.t him noting the OP's proxy is from Kansas even though he is in Reno.

I too have the internet2 APN on my n900, will checkout what epc gives me.

Edit: Looks it it brings the proxy closer to me, but no impact on ping latency as such 200ms or up/download speeds.

I really doubt it. I can pull up "2G AT&T" (works) and "3G AT&T" everytime I scan for service. The "3G AT&T" always says "No access." I don't even think it is trying, actually. If I have the phone near speakers, the "2G AT&T" makes connection noise, but "3G AT&T" is dead silent. I'm fairly sure my old 3G phone made noise next to speakers, but someone correct me if I'm wrong.

Fair enough, but it is not recommended to run VoIP on circuits with latency over 150ms as QoS issues arise.

He may still have been roaming on T-Mobile, without knowing.

T-Mobile bought VoiceStream, which shared GSM network with Cingular at some point. Once Cingular acquired AT&T (blue), the deal was that VoiceStream would purchase that network outright, whereas Cingular would adopt the GSM network from AT&T Wireless Services. Long sordid history, but he bottom line is that with an AT&T (formerly Cingular) SIM, the T-Mobile network will often (and especially on Nokia phones) show as "AT&T".
Though it's certainly not like the 850/1900 international N95 fun we all had.

ok this is whats going on, the n900 picks up tmobiles 3g, you can use up to 25mb's of their 3g before at&t gets mad and sends you a emil and text haha.. and thats per bill cycle.. now i did my research and at&t can not charge you due to the roaming agreement. they just prefer you not use it cause that means they have to pay out of pocket.. the only end result is that they cancel your account or line free of charge (no deactivation fee).

I just checked, and I have T-mobile 3G coverage in my area (100% positive). How come I can see "3G AT&T" but it will not connect to it? Additionally, I see nothing about T-mobile 3G. I'd love to use the 25MB / mo, no problem as I am almost always using WiFi. I just don't like missing calls when my n900 is connected via EDGE and calls cannot get through! Is there anything I can do to get the n900 to "roam" on the T-mobile 3G network?

Mmmm the data should suspend and let the call through. Does it happen all the time? I'm on at&t with Edge and I've never experienced this..

Up until you just asked, I have never directly tested it. I always based it on receiving text messages where the sender said "I just tried to call you..." and I noticed my phone was syncing my large email accounts.

So to reach a more definitive conclusion, I ran speakeasy.net's speed test and tried calling my own phone while it ran. Five (5) times I was connected to voicemail after just 1 ring. Once the test was completely done, my 6th call got through and the phone rang.

I would say it is consistent, reproducible, and it only happens when a data connection is open for a lengthy (5+ sec) amount of time (not just when the "Data Connection" icon is visible). I think it is based on actual data flow, not just an established connection.

I also tested a SSH session. It could be interrupted, but only if I was just setting at the command prompt. Having a program with consistent terminal data flow, i.e. "top", would block calls from getting through.
