Hey everyone - good news. Both my cradle that I mentioned and extended battery+VZW door has arrived on the same day (and fit in my apartment mail box
) !
I haven't been able to test the battery out yet - I just got home and just put it in the charging cradle battery slot laying "flat" - it fits perfectly. The Sprint CDMA with the slim OEM battery fits on the slanted part of the cradle perfectly and both were charging. I am going to charge the extended battery overnight and see how the VZW and extended battery fit/perform tomorrow and over the next day or so -
Will report back in a few days -
edit 1 - ***
VZW door fits fine on this Sprint CDMA -
I removed the plastic support slant by pulling upwards - too fast or hard might break the support tabs that seat the plastic piece into the cradle if you ever want to put it back. The "plastic support slant" and the extended door and batter WILL fit if you direct the the male/female ends of the cradle to phone. Also the slim OEM battery and stock sprint door will fit back on the "slant" side WITHOUT the plastic support - I suppose just don't tap too forcefully (i.e. when typing) on the phone with the style - seems okay by just pressing lightly...
Will update later on the battery performance - using sharkie rom 6.5.x which already has improved battery life on the OEM slim stock sprint battery.
