Yes, it can be depressing.
No it's not covered under warranty.
We know it happens and Mission Repair is here to help. Read below for a few details.
You can choose to buy a new replacement iPhone at full retail (check it out, it's not cheap!) or you can choose the experts here at Mission Repair. Our process and exclusive iPhone 3G Adhesives are one of a kind and are the BEST way to
install a replacement glass panel into an iPhone. Trust us, we've repaired THOUSANDS of units and have sold cases of adhesives to dealers around the country. Other repair centers try to "glue" the new glass/digitizer panels, which is a bad idea. Glue can seep into the home button cavity and then render it useless. We've also experienced outgassing issues with liquid or gel adhesives that can literally eat away at crucial components within the iPhone over several weeks or months.
