Nearly three weeks after Opera Mini 6.5 graced the Android Market, it's now ready for iOS, BlackBerry, J2ME and S60 (the latter's in the form of Opera Mobile 11.5). The download, which is no different than what we saw on Google's mobile OS, brings with it an option to keep track of the amount of data you've used. This type of feature seems to be catching on all over the mobile world as more and more companies continue to switch to capped internet plans. If you're looking for this option, it appears as a dedicated page within the browser's help menu. Now is the time, Opera fans, to go forth and save data.
