Summary: I had one of these phones for about a year and the hinge spring failed. It was difficult to stay on a call without it hanging up by the flip closing. About 2 weeks later the right side of the hinge broke. I replaced it with a used phone from Ebay and plan to use it until my contract expires. NO MORE Sprint/Nextel phones or service after this. This is my fourth Motorola military spec model and they have all sucked.
Excerpt: What a piece!! After spending alot of money you would think this was going to be well worth the investment, think again. I am on my second phone now after owning the first for 2 months, the hinge broke the screw so the flip was wiggling all over, the HUD display was confused and rarely worked, the factory plastic abs holder is pointless unless you want to lose the phone somewhere. The reception goes in and out never a steady signal.
Excerpt: I own an i680. Had an i580, and wanted to upgrade. This was no upgrade. Besides being pretty expensive, unless signing a 2 year agreement with a carrier, the holster made by Motorola allows the phone to fall out repeatedly, which caused the phone to break. The right hinge broke from falling out of the holster, and dropping the less than 3 feet to the floor. I have been investigating this issue, and I am finding out that it is a VERY common issue!
