Ok, I've read some posts about this situation and I talked to a colleague who used to own a RAZR. Over time you'll start to notice your phone gets really hot. Then, just past your warranty, you'll start to notice the back become squishy an begin to bulge (this is where mine is @ 17 months.) According to my colleague, the next phase is the battery stops holding a charge. I've read several posts stating that's what's happening to their phones. My colleague said the next thing to happen is the battery will burst and leak fluid all over. At this point, it's all over and you need a new phone. For my colleague and her husband, this happened a week apart when their phones were 20 months old.
I think Motorola and Verizon should issue a recall and provide an early upgrade option or a "loaner" until the contract renewal. It's the only right thing to do.
