Sprint turned on Spark in my area in mid-February (Alexandria, VA outside of Washington, DC). I am on Band 41. However, I am getting only about 5 mbs download speed and a tenth of that upload. That seems to be the same speed as un-Sparked Band 25. Has anyone else noticed this on the G2? Is there a way to increase the speed on the phone? Or do I have to wait for a network upgrade. In that case, I thought the network upgrade was Spark. Apparently not.
