for those who dont know this...

If you sign up for cingulars $20/month unlimited access (Medianet unlimited) for your cell phone (IE: you have a qualifying phone such as the razor/lg500 etc). Cingular CANNOT tell the difference if you are on your phone or on your nokia.

all of cingulars dataplans are "on your honor", the only thing that changes your charge is the contract (what you admit to).

As far as their network is concerned, they see your phone connecting, not your handheld.

Teathering is a feature of your phone, not the plan, when you teather your nokia to your phone, the nokia is getting internet access from your phone... you phone inturn gets it from cingular. Cingular sees it as only your phone getting access.

I've been on cingulars $20/month plan for months and use it all the time, and have never been charged a penny in connect charges. (so this isnt hear-say, I Personally use it and have checked)

and fYI: these are the numbers i get (download/upload) on my lg500 :

GPRS network = 50K/32K
Edge: 100K/150K
3G: 400K/500K

and yes, i get better upload than download speed for some reason.
