Welcome to AndroidForum, Dulce14u!
So, you just need ROM link / page that is pretty simple to install or need other details about flashing, etc.?
xtrROM is pretty straightforward:
[ROM][GPL] xtrROM5.0.1 odex,cache2cache,apps2sd,jit,lwp,oc[3/29/2011] - xda-developers
(there are optional things you can flash, but you don't have to).
Same deal with xtrSense (from the same dev):
[ROM][GPL][3/15/2011] xtrSENSE5.0.1 [cache2cache,apps2sd,oc,jit]-HTC Sense - xda-developers
GSB is actually really cool and only has two main things to flash (the ROM and the Google apps):
[ROM][6/23] GSB v3.6 Odex/De-OdexFIXED | GB 2.3.4 [CM-7.1.0 RC1 NIGHTLY] - xda-developers
and last, but certainly not least, all the cool kids
seem to be installing Condemned Soul's CM7:
[ROM] 6/23/11 Condemned CM7 V12 CM7.1 RC 1 - xda-developers
I'm sure a few others will reply back with their more relevant feedback than I can give.
Good luck and cheers!
