I am in Canada but because I wanted to save a couple bucks so I got the T mobile G2. I just realized when I was trying to use HTCSense.com that T Mobile G2 doesn't have it. I am just wondering mainly about the GPS part because some people said it uses the SenseUI. I dont have data plan and I was wondering of the T mobile G2 I can use the GPS without using wifi. I just got this last night but at home I can use the GPS navigation with wifi but on the road, the maps are not showing up well and cannot find my destination. Basically for the GPS part should I go for the HTC Desire Z because of the SenseUI?
