If I return to Sprint's latest PRL, I get download speeds of 140 kbps and upload speeds of 120 kbps.
Flashed the Verizon 00002 PRL. Sprint hasn't fixed the issue in well over three weeks.
It says it's on Sprint, but Roam Control *tethering via EasyTether* says Verizon Wireless and my data usage shows I have used over 1.7 gigs of roaming data. Hur hur hur.
