I recently upgraded my Verizon iPhone from 4.2.6 to 4.2.8... It was jailbroken on 4.2.6, but I haven't gotten around to jailbreaking it on 4.2.8. Before the update I used TetherMe to use the native personal hotspot with my unlimited data plan. After the update, it seems that I still have this capability even though the phone is no longer jailbroken. Has this happened to anyone else??
