Twitter/LJ Clients Question

since either I can't figure it out easily or it's not possible to retweet things from the Twitter site/timeline (Twitter.com) while adding a comment .... ie saying: blah blah RT @someone ....' instead of just RT @someone...' Is there a good Twitter client to download? What about one that works on Android phones, too?


and I'm still curious about a good LJ client for my phone....I had one but if I stay logged in, it doesn't let me select a userpic. If I log out and then back in for each post, then I can pick a userpic but that's annoying :P
