DaVinci/Wotan get their firmwares quicker than SEUS, as theyre put out to trial & test.
The firmware you've just upgraded to has been around 4/5 weeks now, and its annoying, as I want the new firmware. But its still not on SEUS goddamninfindifnslngflsds
I would upgrade using Wotan, heck I even have the credit but... I'd have to unbrand my Three handset and would then lose the 'Three' certificate & lose access to MSN
