out box, N900 was using internet2.voicestream.com for its APN. It worked fine but i've changed my APN setting to epc.tmobile.com.

Do you guys know which one would be appropriate one (faster?) to use on N900 with 3G connection?

What differences do you notice? Maybe try a speed test and compare the two APNs..

Best idea. Try it and let us know.

I can't give you speed comparisons, but I can say that all the 3g devices shipped by tmobile generally use the epc APN. That seems to be what they prefer these days.

So you can get 3g from a 9.99 plan?

You get 3G where there is 3G. You can have the 29.99 data plan but if you dont live in the area that provides 3G, you're simple throwing your money away.

Ok, well I want to add data for just myself on a family plan, and Im thinking the only way to bypass getting the 24.99 plan is just changing my phone on the tmobile website to the shadow or something and asking them to add me to the web2go plan which is just 9.99...But it would be pointless if there was a limit like 5GB or something, even though it says unlimited. And I couldnt get 3g. Some have said you will only get EDGE, so slightly confused.

i dont think there is a limit to 5gb and yes you can get 3g on 9.99 plan and someone said on tzone also, if there is 3g in your area like above post stated,
i currently have 9.99 unlimited web for dumbphones, running on internet2.voicesteam.com. i am in ct my 3g speeds are between 700 and 800

I have the grandfather data plan, $5.99 and still access the net fine. There is no 3G in my area so I dont get it here but when I went for the Thanksgiving holiday to pittsburgh, I was able to shuff the net on the Tmobile 3G net with no limit whatsoever.

Just making sure, dont want to charged for overages or anything siilly
