Sorry, posted this in the wrong forum...

I'm hoping someone here might be able to clarify this for me. I'm successfully using the proxy method for internet access via the $6 Tzones on the Tmobile plan on my iPhone in the U.S. I have my APN set to wap.voicestream.com with no username/password. I'm currently travelling/roaming in Canada (connects under Rogers Mobility) and I 'thought' I would be safe from any EDGE connections with these settings. I'm in Nova Scotia (Halifax) right now and when I was showing my iphone to my friends here, I suddenly noticed that my weather updated! I looked under the Fieldtest and sure enough, under the PDP information, I was getting an assigned IP address! There were no connectable Wifi signals at all and I was definitely on Edge, and not Wifi. Scared the heck out of me (I'm frightened by any possible roaming data charges) and immediately went in and erased the APN voicestream address. I don't seem to be getting EDGE anymore now. Tmobile's website doesn't have my last 48hrs of unbilled usage info yet so I can't find out if I'm being dinged for roaming data charges yet. Is this normally what can happen with Edge? I thought that leaving my original wap.voicestream.com APN settings wouldn't have allowed me Edge access while in Canada and thought I was safe until now....

So, is the reason I was getting EDGE because Rogers recognizes Tmobile's voicestream APN? My understanding (or lack of) was that I'd have to have a valid APN in the box for EDGE to work. The two iPhones I sent to my brother who lives up in Ottawa are also on Rogers (with a Rogers simcard), but it has the default Cingular APN in the Edge settings that came with the US-bought iphone, and I was under the impression that he shouldn't get Edge since Rogers wouldn't recognize the Cingular APN... so far it doesn't appear that he has ever gotten Edge to work up there (knock on wood).

So, other than keeping a close eye on the Edge, is there anything else I should do to protect myself? Am I safe now that I have taken the APN out of the Edge APN box? Or should I put something else in the Edge box (like the Cingular apn?). I have gmail setup in the phone but I've made sure that it isn't constantly updating/checking. Sadly until 1.1.1 is unlocked I'm stuck without the ability to solidly disable Edge...

Any insight would be greatly appreciated...
