I was really excited to find a leaked copy of OS 4.5 for the 8310 late last night and stayed up to install it. Once I got everything running though, I was pretty unimpressed. Aside from the video and voice recorder there's not really much else in this update that changes the look & feel or usability of the device.
I already have html email with empower and actually prefer the options in that app to the native implementation. Word document editing is cool but it's just a 3rd party app. Media player is still slow and no gapless support. No real notable improvements to mail or browser.
This was supposed to be a 'big' update but it doesn't seem that way and there's nothing in here that's going to put the blackberry OS experience on par with an iPhone anytime soon.
If anything, I hope this update allows me to use a 8GB microSD.
