Done my 3G which was on 3.1.2 last night with Redsn0w, Liking the ease of use of the catorgories, multi-tasking doesnt seem up to much as the screen refreshes in most apps which takes a couple of seconds to respond.
Got my Veency and PDA net back on and both working fine, overall not much to write home about at the min because it hasnt added much that I never had covered with jailbreak apps.
