None of the reviews of the 2125 have mentioned whether or not the hump actually seems to improve reception. I know some people with the SP5m that have complained about the quality of the reception. I get annoyed with phones that aren't good phones (if that doesn't seem obvious enough), so it is important to me.
I have T-Mobile US and have been trying to figure out which smartphone to buy. I like the SP5, but I'm curious if there will be a non-Cingular version of the 2125 that has the hump and WiFi. Is there any news about this type of model?
