You will probably have to switch to clockworkmod 2.6.0.1 or aman ra 2.1.1. If you want to flash custom roms. Unrevoked jumped the gun with their 3.0.0.5 recovery betting that all the rom developers would switch to the newest scripting language. Depending on which unrevoked you used you may or may not need too. They changed the recovery today to use 2.6.01 to correct the errors people were having. Anyway, the easiest way is to download rom manager from the market and see what recovery it says you have. If it says you have clockwork 2.6.X.X then your good to go, if not you can use rom manager to flash an alternate recovery, aman ra, or flash clockwork 2.6.x.x
