There was already a leaked Sprint spreadsheet at the beginning of June showing off a couple of phones coming to the carrier and it appears that a new version of the document brings some more hints regarding phone release dates.
If the information turns out to be true, you can expect the BlackBerry Bold 9930 and Torch 9850 to arrive on August 21, similar to the previous leak. The BlackBerry Curve 9350 is listed with a September 9 projected launch date but the LG Optimus Slider LS700 (AKA, the Gelato Q) has disappeared from the list, probably being delayed or cancelled.
Also there is the Samsung Conquer D600, previously leaked by Sprint itself. It is listed with a projected launch date of August 21 while the Motorola Photon 4G is set for a July 31 release, exactly how Sprint itself previously confirmed.
