Hi Users, this is Adnan. 

I, now, have started to focus my bitlander blogs more on about IPHONE n IPAD stuff and app reviews, to make you guys more productive as well. 

Satisfactorily using iPhone 3gs (jailbroken) and iPad mini ( jailbroken as well ). 

For example. this is the tweak I use to write something on the screen of iPhone or iPad and then take the screen shot ( by pressing HOME + SLEEP / WAKE button on top right of iPhone/ipad.)

Tweak is called "iwhiteboard" you can search it on CYDIA , if your device is jailbroken. iOS 6. I'll look whether iwhiteboard is compatible with iOS 7 or not.
