My Titan (replacing an Apache) comes today, need a little info

[DougWare]

My Titan is coming today. I've already cooked a new WM6.1 rom for it, but I would love to upgrade the radio at the same time.

Can someone please post a definitive answer on what the newest radio that supports REV A and working GPS is?

Can someone tell me any downsides to this radio? For example, 1.43 is the newest on the apache, but it's caused me a few problems and once I went back to 1.41 everything was ok.

Thanks!

Doug
