Sprint 4G users, your data is about to get a bit faster if this internal flyer is anything to believe. Starting June 10th (that’s tomorrow), Sprint will raise the 1 Mbps uplink speed to 1.5 Mbps. To take advantage of the heightened speeds, users won’t need to download any software upgrades – just wait for it to happen and BAM! Too cheesy? Yea, I thought so, too. Note that this only applies to mobile phones. Sprint Overdrive devices (USB sticks or WiFi hotspots) are not on the guest list. [Spantecular]
