ok so i just tried the ro.ril.hsxpa=5 line and this is what i got...
before i did the tweak
-from the "wifi settings" menu i turned on wifi and counted the time it took until it was connected.(5 times)
it was 16, 13, 11, 10, and 12 seconds respectively.
-3g speed before tweak according to speedtest.net:
ping:433ms download:30kbps upload:78kbps server in ashburn, VA
-wifi speed before tweak:
ping:46ms download:3563kbps upload:775kbps server:ashburn, VA
after i did the tweak
wifi time to connect:
9, 9, 10, 8, and 10 seconds respectively
-3g speed after tweak (it switched servers for some reason...)
ping:392 download:60kbps upload:146kbps server:frederick maryland
-wifi speed:
ping:87 down:2516kbps up:718kbps server: frederick maryland
so it looks like my 3g is faster, but my wifi is slower. i dunno if the tweak changed the server or what, but it was different afterwards. i loaded a few pages in the browser and idk if it was my imagination or not, but they did seem to load very quickly
