How often do you leave an iPhone 4s on its charger?

I get mixed answers that if you leave your iPhone on its charger all the time it'll hurt the battery while other people say it won't do anything to the battery. And to be honest I often hate having to charge the battery when it gets really low. Would rather just leave it plugged in unless I'm going out somewhere with it.

IPhone 5 home button water damage?

Which is better? Nokia Lumia 620 or Nokia Lumia 520?

I'm trying decide which is overall better between the two Nokia Lumia models, I just need a phone which makes calls and texts (well, duh), has wi-fi so I can use Facebook, youtube, browse the web and the occasional Xbox/Windows Phone game and has a decent camera and Nokia seems to be in my price limit, before I get the "Get the iPhone/Android Phone/Sony, etc" answers, don't even bother, I've been hearing good things about Nokia, I like the Windows 8 design, and I just want to know which model is better between the Lumia 620 and Lumia 520, Thanks

What is a cheaper alternative to getting a patent on an idea?

Hi, I recently had an idea for an iPhone app that I intend to sell on the app store. I'm hiring a developer to create it for me. However i'm a bit worried that he might steal my idea, I have researched into patents but i don't have the $1000s required for it. I was wondering if there was a cheaper alternative that would still give me legal ownership and authority over the app idea? Also do i really have to hire a legal authority to write my patent or can i just write it myself and how much money would i save in doing so?
