Does it matter what type of phone you use?
Is there a more ideal one then a spare LG OV ???
As long as it has adequate internal memory and a screen that's appropriate to the apps you're building. My choice six months ago was the Motorola Atrix, which is on a par with the HTC Sensation and the Samsung Galaxy II, but is smaller, has more memory than the former, a higher screen resolution than the latter and was much cheaper than either (I use Pay-As-You-Go so I always buy my handsets outright). These are all dual-core handsets. There's a new batch of quad-core machines but I don't think they offer much extra for a developer.
Separate names with a comma.
