HSUPA

With just a day left in April, AT&T made good on its promise to enable HSUPA for its two newest HSPA+ enabled smartphones, the Motorola Atrix and HTC Inspire 4G, before month's end. The two phones both originally shipped with HSUPA disabled. As a result upstream throughput was capped at WCDMA rates of 384 kilobits/sec instead of much higher upstream throughput possible with both phones celluar basebands. We've spent the day testing the HTC Inspire 4G to see how throughput has changed, and came away decently impressed.
