Only Sprint could deliver a camera phone, chock-full of Sample Pictures, which are LOCKED and you cannot DELETE, so you can't take more than ~6 pictures.
And their tech support has no idea how to unlock/delete them.
Innumerable forum threads asking how to delete them exist.
And the only solution appears to be to download the phone OS, hack into it with a JavaLoader or by mounting it on your computer, finding some oddly-named .cod file, and deleting that file before you install the OS.
But the name of the file is version-dependent, and deleting the wrong file gives you a dead phone.
And, really, how tricky can it BE to give users an "unlock" button or just make the sample pictures not locked in the first place?!
