I heard that it is possible to get the lg vx8100's Bluetooth to work with a PDA. Anyone out there know the how of this and if it would work with a Dell Axim x51v? Or should I forget all that and just get an i730 smartphone? That idea scares me as I'm a realtor and need some serious kickin' battery life to my phone and heard that the i730 is a little lax on battery life.
