I recently got wi-tribe and was looking for speed test results of wi-tribe with speed boost before getting it but didn't find any, i got it anyway and ran some tests on different servers:
on Torrents: Around 180 KBps
Before Speed Boost the results were around 1 - 1.2 mbps (speedtest.net) and 100 - 120 KBps (torrents) , so its a decent improvement. The tower is very close to my place so getting full signals and pretty much satisfied with speeds.
I just wish they offered an unlimited plan or at least something close to 50 GB, anyway i guess ill have to do with their Up-size promotion and buy 10-20 GBs.
P.S. If anyone knows how long they'll have this Speed Boost and Upsize promotion running for please let me know.
