This is the series of phones I personally have been through in the last 6mths (mostly in the last 6weeks).... in fact my Eris is slowing and rejecting more apps as the days progress... and now my wife's phone is also on it's 3rd re-incarnation (battery failing) and won't survive more than 2hrs without charge.
I was this close to going back to a Windows OS phone.... but now I hear the current ones are... well lets just say they make nice table ornaments 
Is anyone else having these kinds of issues with useless replacement devices, one after another? Is anyone experiencing a slowdown of their Eris? Why are the apps failing???
Any input appreciated.... (I've already written to BigRed.... waiting for a reply)
