same here dude, my profile changed at 2am this morning, I lost sync and my phone made a weird noise, and i thought WTF has happened, but i had just settled down to watch some tv before going to bed and I didnt bother to check my profile til this morning.
the router was left on for 2 days and 6 hours or so and the profile went up from 6500kbps to 7000 kbps, thats a big jump as I now get 800kbytes + steady instead of 730 or so, basically back to my old speed, its still a touch slower but nothing that I am guna complain/worry about, 800 was the magic number for me
btw, its good to see your profile has unstuck itself and went up
