Some believed that due to the immense level of anticipation for firmware update 2.40 that we may encounter downloading problems. You know, if the servers got all jammed up because a gazillion users were trying to obtain the new update all at once.
However, despite a few reports of users getting errors when trying to log in, or errors during downloading, it seems obtaining firmware 2.40 is a pain-free process. It'll depend on your Internet connection, but this is hardly the largest or longest firmware update we've seen in the PS3's history, and we haven't come across any reader complaints of server unavailability. Also, on that same note, there doesn't appear to be any problem with 2.40 itself. In the past, we've heard plenty of nightmare stories about updates for either the PS3 or Xbox 360 completely "bricking" the system; in fact, Sony has been known to issue more firmware updates simply for the sake of fixing what the last update did (update 4.01 fixes 4.00 for the PSP, for example). We've heard about multiple freezing issues in the official PlayStation message boards, though, so we're a trifle worried that whatever this problem is, it could be widespread. But it doesn't appear to be a major issue…yet.
In the end, we've heard of people actually saying they'll wait to get 2.40 after the craze has died down, but we assure you, there's no need to wait. And even if there was, the craze would've died down by now. So go! Get! Enjoy!
