I tried flashing the HD ROM but i kept having random reboots. I have wiped and reflash a couple of times but still...same. I havent even restored anything from Titanium Backup yet.
Any suggestion what could be the problem??

I have been using baadnwz ROM for awhile with no Data2Ext. Had a couple of FCs on first attempt but no more problem after reflashing the latest version. So far so good, except the obvious 720p recording problem.

Hmm..I flashed the latest radio and my phone suddenly can only show the "G" sign instead of "H". Flashed back to the old 32.48 and the "H" sign is there again. Could it be the problem of radio or what...??

Well, alot of ppl chose to buy Desire (including me) at the first place is because of the sense UI. If not why not buy N1 instead. Yeah as we become more pro and pro we might start thinking that sense is nothing but a clutter of crap, but its still the best launcher made by any phone manufacturer. Touchwiz or Motoblur or whatever are not even close. There are widgets out there which are just emulating Sense widgets already shown that how handy they are.

My point is, its really a matter of preference. Depends on what u do more with your phone. I am not even using a Sense ROM currently myself, but I would say majority of Desire users out there will always choose Sense over AOSP ROMs.

So yea..advanced users dislike it but IMO Sense, and all custom made UI are crucial to Android development, at least until now. Do u think Android can reach its current popularity if every single Android phone out there had been using vanilla Android?

P.S. am patiently waiting for a Sense+Gingerbread ROM. Haha.
