I have a company-supplied Bold, and it is easily the worst phone I've ever touched. Its not reliable at ALL. It only syncs when it feels like it, reception is poor, and the battery life is so bad its never charged anyway. And for some reason, if the battery starts to go low, it just turns off the cellular modem but doesn't turn it back on when its put back on charge. Basically, if you keep one eye on it, it'll just stop getting emails.
The innovative ways that Blackberry devised to suck are impressive. The battery life is about a day (if you don't use it), it doesn't really have a keypad lock as its designed to live in its huge holster, the speaker phone is so bad its useless (the one in my dumbphone Samsung Convey is immensely superior), it has a gazzillion buttons that I don't even think do anything, etc.
Maybe OS 10 is an improvement, but the older versions are so hard to work its not funny. There's Setup, Options, Preferences, and then individual options and preferences in each application it ships with. If you want to change an email option, which of the five options menus is it in? Well, just try them all. Mine's stuck with the French spellcheck library, but I can't find the option to fix it. I found the one for the whole phone, which is set in English, but does that affect the spellcheck? Of course not. Oh, it must be under the "SpellCheck" options menu. Nope, not there either.
The funniest is the charging. When you plug it into a PC to charge it, it lights up with this nice clock thing. Put the PC to sleep, and it'll stop charging. But its still connected to the PC, right? So the clock thing stays on. In an hour or two, your battery will be dead. Even though its getting power in the USB port.
Maybe they should have sold phones that people wanted to use rather than positioning themselves as the provider of phones that your employer makes you use.
