According to a recent comScore report, it appears that the T-Mobile G1 has become the biggest money maker for T-Mobile. For most, this may not come as much of a surprise, but the reason behind the biggest money maker title is not just because of the phone itself.
First of all, the G1 is the device that currently brings T-Mobile the most money, however that is not necessarily due to the $179 price tag. In fact, the G1 is only the 8th best selling T-Mobile handset. Instead, the biggest money maker title comes from the monthly fees. Apparently, T-Mobile customers are more than willing to pony up for the extra required monthly data plans that come with the G1.

As for other carriers, with little surprise the same title goes to the iPhone with AT&T and the Storm with Verizon Wireless. The biggest money maker for Sprint is currently the Instinct, however some are speculating that the Palm pre will assume that role once available.
While its great news that the G1 is doing good with T-Mobile, it would be great to see other carriers launch their own Android devices and have those devices be their top money makers.
