The only thing worse than waiting on slow “4G” speeds on the Motorola Atrix 4G is waiting for AT&T to deliver the promised update that will lift data speed caps on the device. If you have a rooted Atrix and are sick of holding out for AT&T, today is your lucky day. The folks over at XDA have once again delivered, bringing a new flash-able radio update that will enable HSUPA support on the dual-core handset. The new radio file was pulled from Telstra’s 1.4.2 update for the Atrix and brings the radio to baseband version 1.87.
Users who have already taken the mod to task are reporting upload speed increases from 0.3Mbps up to numbers bordering on 2Mbps. a major upgrade indeed. AT&T had initially said the official Atrix update would land in April, though time for that is quickly running out. See the source link below for instructions on getting your Atrix up to speed.
