Hi there. I'm using my N900 on Fido and I can empathize with you. However, I don't think I'm experiencing the WiFi issue and I do have the latest firmware. What I have found is this...some public hotspots "confuse" the N900 and won't connect, unless you create a "Connection" for them through Settings > Internet Connections. Then they will connect. In my opinion, it's definitely an N900 issue, since my laptop doesn't have such a problem.

While this might be the phone's fault, it seems to me Fido's voice mail and text services seem to be non-standard. I noticed this when I switched from Bell. Even so, the timestamps on my N900 do look correct.

This is definitely not the phone's fault--it's your wife's fault for being in Canada! I'm in Canada and I think it's ridiculous how the carriers here are gouging their customers. I refuse to have a data plan, but my boycott doesn't seem to be having any effect.

I also bought my N900 in the USA and it is not compatible with 3G data service in Canada. The best I can get is so-called 2.5G. Also be aware that Nokia Canada will not service this phone because they are controlled by the Canadian carries and no Canadian carrier sells the N900. Your wife, me and hundreds of other N900 users are personnae non gratus in Canada.

Cheers!

Brad
