Once you have retweeted, you can visit your tweets to show all your tweets and retweets. At the upper right of the post you retweeted, click the little arrow button and select 'copy share url' and voila. Note that this will give you the link still similar to that of the original tweet, but the last values are different. If you want to get a unique one with your profile name on the link, I will suggest you use mobile twitter application to get the link. (That is what I do anyway). Cheers!
Okay thankyou for explaining me this...thats a nice idea to use mobile for thatBy mobile, I meant Twitter Mobile App. At least I use the Android twitter mobile application to generate my retweet links. For instance, this is a retweet link I just generated from my account @tosmartak
