Some thought Sprint was teaming up with LG to launch a killer WiMAX smartphone at CES but the big press event came and went with nary a mention of an LG-branded WiMAX handset on the horizon. A leaked inventory list from Sprint reveals that we all might have been barking up the wrong tree. First on the inventory list is not an LG phone but the HTC A9292, an Android-powered WiMAX handset with a candy bar form factor. HTC already has one WiMAX phone in its portfolio, perhaps the A9292 will become the second. Our unknown friend, the LG LS680 makes its second appearance on a Sprint inventory list. The LS680 will be an Android handset which the tipster claims is similar to the GW620 Eve. Also making a second appearance is the Palm C40, an unknown device that was originally spotted in Sprint’s inventory last August. The tipster leaked additional information about some new handsets that do not appear on the inventory list above, too, so hit PhoneArena for the details.
