I used to frustrate over how I can’t share a video from any video sites such as YouTube and etc from my iPhone. 

Here’s a TIP: 

COPY this: JAVASCRIPT

When you open this post on your iPhone, Press and hold the JAVASCRIPT link and copy paste it in a bookmark on your iPhone. (create one from any site and name it whatever you like and save. Edit the bookmark and paste the code to the link bar and voila!) make sure you edit and paste on from http://gossip-live.com/”javascript:var…”

You can browse and share anything from any website you browse on your iPhone. No more waiting to get to a computer to share that Youtube video to be posted on your Tumblr rather than posting it as a link. 

i.e: Open Youtube or any video-sharing sites from safari….

Scroll all the way down and click the “Desktop” link to open the web version of Youtube.

From here, all you need to do is hit that bookmark icon and you’ll figure the rest out I’m sure of it :) feel free to comment or ask if you have any questions.

(Additional Tips: You can watch HQ YouTube videos on Safari for iPhone on 3G, incase you didn’t notice that you’ll only get HQ videos using the the native app on wifi. This is because Apple sets the quality on 3G to avoid the expensive charges or whatever BS, I mean why don’t just put a button for HQ and Low quality settings??).
