Verizon and casio have locked this thing down quite well, however, just like with all the others, there is usually an app that is preventing unadulterated tether. I was removing apps to see what happens and after doing a free for all on the apps i decided to try the tether and i didnt get the dreaded verizon screen saying i had to conform to their standards. The only problem was i was tweaking with the modem so much that now it wont connect to any cell tower. Had to return to stock and will get another one...without tweaking the modwm this time. Interesting side note - after full wipe and all modem settings to factory i got SIM CARD MISSING. I believe they had this phone made without the sim card slot, but from one of the photos under the " white tape" on the back (posted on phandroid), I thought I saw a place where you could mount the sim slot. The battery would have to be slimmer though....just an observation. I also think the japanese version does have a SIM, and the TYPE-L definately has a SIM...thats the one I am trying to get from Japan.
