Anyone good with identifying what's in a tower?



Best picture I could get, Its the one tower I connect to at home.
It is not owned by T-Mobile, Its leased by SBA inc.
AT&T/Alltel/Verizon all show 3G coverage here and its pretty much the only tower around so im guessing this tower is packed with their equipment.

Any idea which one of those is T-Mobile's? This tower is GPRS on T-Mobile.
