I have 4.5.621 and 2.3.4 and i just did a root using the [How To] Root 2.3.4/4.5.621 with magic md5 (does not require Milestone SBF) - Android Forums magic md5 method apparently.
How would i now go about installing a custom rom, and which one should i use? I've only heard about liberty and miui. Could someone walk me through this? Again i'm very new to this and would love for my phone to run a little quicker and have better battery life.
