Dunno how often Mr. David Chang visits this forum, but if you do see this, I have a question for you.

With the recent release of the Samsung IP-830W on Sprint and with Verizon carrying both the i830 and i730, will you be releasing extended life batteries for these three PDA phones?

All three (Sprint IP-830W and Verizon i830/i730) use the same batteries. Right now, the only company offering 2400mAh batteries for these units is Mugen and their prices are very high though and they have problems with pain quality and the batteries eventually expanding and bulging.
