Hi all, hope you people find it useful.

Remember to follow exactly in order to achieve the desired result.
I am using the following:
Iphone 4S IOS Version 1.6.3 Web browser: Goggle Chrome
1) Open your notes apps that can be found inside your iphone.
2) Type the comment that you wish down
3) Upon finished. Tap once on the comment.
4) Select the option " Select all".
5) Select the option "Copy".

6) Tap once at the scale icon found at the top right corner of the post that you wish to add to rep.
7) Tap once at the comment.
8) Tap the option "paste" and "done" to close your keypad.
Note: Do not panic as the option box "add to rep" will "disappear".
9) Tap once at the scale icon of the selected post again.
10) Tap once at the option "I approve" or "I disapprove" with your comment shown.
11) Tap once at the option "add to reputation" to complete the up/zap.
I do not own an android phone so I do not have the means to test this method. If anyone has another way to perform "add to reputation", feel free to post over here.
Latest update: S4 running android 4.2.2 with positive result.
Sharing is caring. Have a great day.
ps: Show your appreciation by giving me your virgin ups with my method on your iphone. Your support is much needed.
