Or in the case of my Samsung Moment, the Radio Interface Layer is flaky and will cause random data lockups. Samsung officially stopped updating the phone back around May (yay, 8 months of support from release date!), so even if I could continue upgrading my OS without their help, nobody will ever fix the hardware driver, it will always randomly lock up.
