Little after people started receiving their Nexus Ones the complaints went out. Most of those complaints were that the 3G signal was weak and somewhat non exsistant is some spots. The customers that are shouting out t0 T-Mobile and Google are the loyal Android users that had a G1 or MyTouch and know what they were receiving before.
Our friends over at TMoNews have found that T-Mobile does acknowledge the problem and are actively looking in to the problem. Google has yet to respond to any issue.
