It has been awhile since I have seen a carrier officially release an OS 5.0 build for the 9530. This latest OS 5.0.0.419 was spotted by the team @BBRocks and comes from MTS Mobility. Hopefully it improves upon other builds.
Please confirm in the comments if this works for you
NOTE: Don’t forget to delete the vendor.xml file located in c:program files>common files>research in motion>apploader to install it on a different carriers device.

Great update, much improved keyboard glow feature, plus pop up keys are back with three options always on, on hover, and never. So far thats all I can tell. But still great update IMO

Video player doesn’t play back DivX 4, DivX 5/6 or XviD anymore!!
This is a huge letdown, since I watch videos on my phone often.
Anyone recommend a third-party video player instead?

Just to clarify, I’ve been able to watch DivX and XviD videos just fine on my Blackberry Tour using OS 4.7 and OS 5.0.0.230.
Anyone know why RIM stopped supporting these formats on the Tour OS 5?

My storm 9530 is officially unlocked. Will this upgrade lock my phone to MTS mobility.
