Will there be any difference if you originally using AT900T version 4U4G to AT900T3U5G? Also 3U means more durable than the 4U, is this correct?
yes 3U is more durable than 4U but the difference is a maximum of 5g so you should have little problem changing over.
well.. i just broke my at900t 4u 4g.. so actually i almost bought the fake at900t but as BCF member i think better i bought secondhand at900t than the fake one.. So this second at900t i gonna get is a 3u 5g.. R u guys sure at900t 4u 4g is more head heavy than the 3u 5g? Hmm..
