When BlackBerry OS6 was announced, RIM let us know that only three v5 devices would be upgradable to v6, namely: Pearl 3G, 9650, and 9700. However, the then upcoming 9300 Curve 3G was specified as OS6-ready.
If you are using a 9390 that is still running v5, plug it to your PC and launch Blackberry Desktop Manager. If you have an Internet connection, you will be notified of an available update to OS6. Simply follow through with the prompts to upgrade your device.
The upgrade was hassle-free for me and in some minutes, I had OS 6 running on my device.
So, how does OS 6 run on the 9300?
Generally speaking, the device runs well. It certainly looks better than the plain old looks of OS 5.
However, you will notice lags when you scroll through the Facebook and Twitter applications in particular. Those lags are significant and do get frustrating.
While the BB OS6 browser supports multiple tabs/windows, I often encountered system messages prompting me to close tabs to conserve memory, and in some cases all tabs were closed by the system – including the one I was viewing. Specified as having 256Mb RAm built in, there just doesnt seem to be enough resources to handle my web browsing on the Curve 3G with OS 6.
Still, it generally runs fine. Email works, browsing works – evwerything works minus the occasional lag.
Do you have the Blackberry 9300 Curve 3G and still running OS 5? Feel free to take the plunge and upgrade to OS 6.
