yes you can tether a fully flashed to CricKet; Sprint HTC vogue xv6900. Same as the touch Pro, diamond, and a few others of the HTC family. Also alot of the motorola Sprint cells work on cricket fully flashed and with tethering a breeze. Google people is a very reliable source for anything that your trying to do with a cellphone just as this very site here has done in the past and assuming the future. But do keep in mind that just looking here and asking just in this forum can take weeks, months or feared NEVER results as its limited to how many people here that have the kno how nd field work as to the testing different phones. With all said people do more research I see alot of the same ol questions asked here and dont be sorry for asking for more knowledge on how to.......Just do a lil more researching and try to post results of your findings and not just posting it worked. Some1 else might wanna kno to.
So read all the forums first for what your looking for and if your problem isnt answerred or fixed try google and then post your findings to further help a already greate site. It helps
