Any reason NOT to flash to MR1 on xv6800?

[wackychimp]

I've never flashed my phone before but have done lots to my PSP. In that world you end up with new revisions patching doorways that hackers are using to make the device more useful. So upgrading is not always good.

So that's why I'm a little shy of MR1. Will it prevent me from doing anything "cool" with the Titan down the road? I'll probably eventually move to a custom ROM anyway, but I wanted to be sure before I did anything.

I like what I'm reading here about the aGPS enabling on MR1. Now if I could just get WMWifiRouter working.

Many thanks!
